The web browser is by far the most-used application on the computer.  Hours of listening to music, watching videos, or simply having many tabs open drains your battery and reduces your laptop’s performance.

Our new battery saver is today ready in the stable version of Opera for computersafter we tested it the in developer and beta channels.

Batter saver in Opera browser extends your laptop's battery life to up to 50%

When we first released the battery saver, we got positive feedback from you. We really appreciate that, and today we would love it if you could help us spread the word about Opera’s new battery saver.

Please help us spread the word about Opera’s new battery saver!

How good is the battery saver in Opera?

Last month, we made several tests to find out how the battery saver performs. In some tests, the feature increased the battery life by as much as 50% comparing to other browsers, such as Google Chrome.

After the initial release in the developer stream, some of you have been asking for more detailed test results. Together with the beta release, we presented a breakdown for the the initial tests as used for the developer release.

Longer battery life for your laptop with battery saver in Opera browser for computers

However we know that video works much better than the thousands of words. That’s why we shot a video showing the full test. Enjoy watching this time-lapse:


Beat the heat during summer

There is one more thing we realized recently. If something consumes more energy, it usually gets warmer – basic physics. That’s why your laptop gets overheated during your heavy browsing sessions. This heats up your lap, sets off a loud and annoying fan, and can cause problems such as random blue screens or even data loss.

We’ve made tests comparing the temperature of the bottoms of two laptops. One was running Opera with battery saver enabled and the other one Opera with the mode disabled. Test results with the new battery saver enabled showed that Opera can keep laptops over 3 degrees (C) cooler. It’s actually pretty nice difference, especially when you think about bringing your laptop along for summer fun and letting it bake your lap.

Improvements under the hood

Wonder how we achieved this cool down and power savings? With several under-the-hood optimizations:

  • Reducing activity in background tabs
  • Waking CPU less often due to optimal scheduling of JavaScript timers
  • Automatically pausing unused plug-ins
  • Reducing frame rate to 30 frames per second
  • Tuning video-playback parameters and forcing usage of hardware accelerated video codecs
  • Pausing animations of browser themes
  • Including ad blocker – when enabled, it enables even more battery savings

How to enable battery savings

Using the new power saver mode is easy. Once the laptop’s power cable is unplugged, the battery icon will appear next to the search and address field in the Opera browser.

Click the battery icon to activate the power saver mode and flip on the switch. The browser will also detect when the laptop’s battery is running low and will suggest enabling power saver mode.

Other new things in Opera 38

Ad blocker – add your own lists. You can add your own block lists. To add your own custom list file, head to Settings and click the “Custom Block Lists” button in the ad-blocking section (note that “Show advanced settings” from the “Browser” panel must be enabled to see the button).

Speed Dial improvements. Now, you don’t need to worry that you removed a website from your Speed Dial accidentally. You’ll now notice three little dots on hover in place of where the delete button used to be. The new button provides quick access to the features previously only available in the context menu, like opening in private tab, or removing a website from your Speed Dial.

Add your own photo as theme. A while back, we introduced the “Create your theme” option in the theme manager. Now, this option is more visible for you. Just go to the Customize start page and click the ‘+’ button; then, use your own photos to create a theme.

Extension button visible in the Speed Dial side panel. All extension users will have the extension manager always at hand. The extension icon is visible on side panel on the left side of the Speed Dial page.

Change in version support for OSX. Starting from this version, we’re updating our requirements on Mac. Now, we’re supporting OS X 10.9 and higher.


We are really happy to bring power saver, as the first major browser, to the stable version. Together with ad blocker and the video pop out, it makes Opera the browser that really responds on today user expectations.

Download the latest Opera for computers, and let us know what you think about it in the comments.

    Congrats on the achievement of Opera 38 Stable version release !

    The battery saver feature is the first of its kind found in a browser which testify to
    Opera’s innovation to create

  • Dark Magician

    ”like opening in private tab”

    Yes, I want this. Just it isn’t there yet. 😀

    • Aneta Reluga

      Good catch. Corrected 😛

  • Flavoi

    Congratz guys, this product is getting better and better! Please keep it up 🙂

  • Dmitriy K.

    So, there is no VPN in O38? Damn, I’ve been waiting for it for months!

    • Aneta Reluga

      We have to make sure this solution is absolutely perfect. Please give us some more time.

      • Vlad Violenty

        what intresting you present in O40 ?

        • Aneta Reluga

          I don’t think I’m allowed to speak about future plans at the moment 🙂 However, back to VPN, we are polishing this feature and of course continuously gathering feedback not only for existing features, but also for feature implementation possibilities. Just a bit more patience please.

          • iPristy

            VPN is rather important, i can now drop other browser experiments like Vivaldi, Firefox and Tor, if nothing else i will use VPN in Privat window for now with VPN flag on that’s for sure.

            In other news:
            I have also noticed that you translated Opera Mobile for Android to Slovenian lang. what about desktop, maybe some day?

            Old Bug:
            Opera can’t be registered as main browser on Win7 under Standard user, it’s not on the list of Default programs.

    • Eurock

      It’s here: opera://flags/?search=vpn#browser-vpn
      Works only in private window 😉

      • Dmitriy K.

        Yeah, I know about this. Doesn’t work for me either. I get this on any request:
        The webpage at might be temporarily down or it may have moved permanently to a new web address.

    • tu.iga

      You can find the VPN in latest developer version (yep, still in dev but seems to work well there)

  • Александр Карпенко

    When Opera Stable x64 for Windows?

    • Eroticus

      I can’t wait !!!! xd

    • ratamies

      And what benefits do we get from 64-bit version compared with 32-bit version?

      • Александр Карпенко

        Performance. Chrome 64-bit faster then 32-bit

        • ratamies

          I googled performance differences and I didn’t see any decisive advantage of 64-bit version.

          • Dark Magician

            There are also potential security benefits.

          • Leonardo Gomes

            Like what?

          • Michał Gołębiowski

            ASLR is more secure in 64-bit versions because of a much larger virtual space.

  • Vlad Violenty

    where VPN?

  • Konstantin Paramonov

    Thanks guys, but where did Mediasource flag go? Videos lag when it’s turned on.
    Menu button is now red with a notification icon that won’t go away. It says that I have to download the latest security aid (in russian). Please fix the translation too.

    • L33t4opera

      Hi Konstantin, regarding the --disable-media-source flag, it seems to be removed from the Chromium’s code, and since the Opera is based on that code, it is no longer available in the Opera, as well. You can try to use the “h264ify” extension, and see if it is in some way useful in your case (you can also enable the "Block 60fps video" option) – to be able to install it in the Opera, you need first install one of the following extensions: the “Extension source viewer, or the “Download Chrome Extension“.

  • Giovan Maria Catalan Belmonte

    Stupid question:power saver has no sense for desktop pc ? (electric energy consume, heating..)

    • Aneta Reluga

      Actually it does have sense. It’s just a matter of personal preference there since battery life is not an issue – please check out the list: do you prefer cooler, more silent PC but no theme animations and somewhat reduced tab/video performance, or the other way round? Totally up to you.

    • BK

      Less resources usage means you spare more resources for other apps, or more tabs, if you prefer.

    • Giovan Maria Catalan Belmonte

      Thanks all

  • Dark Magician

    “Full screen is unavailable” on YT, tried clearing cashe etc. Everything is setup exactly the same as in 37, and always gives that error

    • Kornelia

      I don’t have any problems on Win7 , Win10, Mac… What’s your operating system?

      • Dark Magician

        Win 10 64-bit

        • Wando Schneider

          Work for Me. W10 x64

          • Dark Magician

            I tried in Private window, still the same issue.

    • Leonardo Gomes

      I’m seeing this message on developer 39 too but it goes fullscreen anyway.

      • Dark Magician

        Yeah, exactly the same, I reinstalled nothing. Tried on other machines and can’t reproduce. Maybe it’s the scaling in Windows?

    • Gutza G

      Confirmed. I have the same issue. It says that it can’t go fullscreen entirely. Previously, in O37, everything worked fine.

      • Aneta Reluga

        Thanks for your report, it is being investigated.

        • Gutza G

          Just to make things clear, the video is displayed on the entire screen but the video controls do not disappear. We are prompted with the message illustrated in the link above.

  • ktxgio

    thanks a lot for new fantastic release!

  • Eugene Tareyev

    Thanks for another update.
    Please help fixing this bug:
    It’s a Blink font rendering issue that was around for quite some time and it’s very annoying.

  • Otopay Siparis
  • LoverOfLife

    Is it possible to add ?
    1. Clear browsing data on exit
    2. More countries to news (ex. Romania)
    3. Same functionality of dials like bookmarks (ex. open with middle click a dial at the end of tabs)

  • Giovan Maria Catalan Belmonte

    I have only 1 real request for this fantastic browser (the best imho): saving bookmarks in html.

    • Would an option to export data via be a solution for you?

      Why you need HTML and not f.ex. JSON or CSV?

  • Momen kamal

    please please help me , vpn problem . when i try to connect the vpn in “opera dev 2248” the vpn won’t connect , “orange” (connecting) , and the vpn still don’t work .
    i try to reinstall opera, remove and install it again , restart my pc , but the problem is still shown , please help me , my work stopped because of vpn , thanks 🙁
    Win 8.1 pro , opera dev 39 2248 .

    • Aneta Reluga

      If you are in a network with specific conditions (e.g. with applied policy restrictions regarding connection through specific ports), or with a very restrictive antivirus (which is a good thing most of the cases), or in using a provider which does not allow certain connections, this may be the result. Can you please say where you are, is it a corporate environment, or maybe if you applied specific antivirus restrictions? Thanks.

      • Momen kamal

        i have bitdefender total security 2015 > i think bitdefender cause this problem, but i can’t remove bitdefender from my pc ,
        i will tell you something , i used opera dev from 2 months and evrything is ok, but when i update opera to the latest version”yesterday” , the problem shown.please help me

        • Aneta Reluga

          Thanks, we’ll try to investigate.

          • Momen kamal

            please, my work stopped because of vpn , we need new update of opera developer to fix this problem , thanks .

          • Aneta Reluga

            Can you please try for the option in Bitdefender that doesn’t do SSL filtering (scanning secure connections) -uncheck it and then see if VPN works? Thanks.

          • Momen kamal

            thaaaaaaaaaaaanks , it’s worked , thank you very match 🙂

  • iYuzver

    I want that the blocker of advertizing deleted advertizing fillers:
    I want that expansions of the browser were synchronized too.


  • babylongreece

    Keep adding new feature but still cannot fix facebook image bug.

    • Leonardo Gomes

      What bug? Images load fine in Facebook for me.
      Once in a while a couple of them may not load but usually a reload fixes it.

      • babylongreece

        When you try to fullscreen facebook image, It will always over enlarge the image and making viewing the image in full screen impossible. Here see the image

        • Leonardo Gomes

          Right, it happens here too.

          • babylongreece

            Hahaha,now you know what i mean

          • Leonardo Gomes

            I may be wrong but I guess it’s not something new.

          • Leonardo Gomes

            It was reported?

          • babylongreece

            Yeap. Already sent a bug report twice plus image about the bug but no reply whatsoever.

          • Leonardo Gomes

            Well, as said on the email you should have received, you will not get any replies unless necessary.

            What is the bug report ID?

          • babylongreece

            Sigh, i know i will not get any reply so i already deleted the email and forgot the bug report ID already.

          • babylongreece

            Hahaha, now you know what i mean. There are more people using facebook than those who use VPN and battery saver yet Opera doesn’t bother to fix this bug. I Opera don’t have Facebook or worse, they use other browser to access facebook.

  • Shion

    Optimization. Good thing to do. Especially after all this time. But turning it into a “one button” feature and “for battery saving” only, instead of making it configurable and applying it at all times, is a bad move. But only heavy users care about that. Your regular twitter dweller won’t give a puck and be all happy and praise giving.

    Best browser for social media? Maybe. Best browser? Nah.

    • Paweł Miniewicz

      Hey, we’ve just started, more power saving features are coming 🙂

  • Alex

    How to turn this on while plugged in?

    • Wando Schneider

      Setting > power saver > Always show power saver icon

  • Nekomajin43

    Guys, have you done any test regarding performance in power saver mode? Is it significant if I have it always ON?

    • Wando Schneider

      AFAIK, nope.

    • Paweł Miniewicz

      Thanks for interesting question. In majority of cases, performance – as in loading speed – is not degraded. You may see drop of fps and some less relevant content might load slower due to JS timer throttling.

      • Nekomajin43

        What about flash contents and GUI response with many open tabs?

      • I am seeing a huge drop in RAM usage with the same tabs & windows from 37 vs 38

  • Cryio

    You can see the difference in 60 and 30 fps scrolling even on this comment thread, with Power Saver on and off.

  • Nekomajin43

    One thing I’ve noticed. You use an ECG-like graphic on the battery on the images in the articles, but the actual battery has a lightning symbol on the toolbar popup. Is it intentional?

  • Didit A. Pamungkas

    still can’t use custom block list..
    Help pls, using list form easylist or ublock doesn’t work..

    • Nekomajin43

      It’s coming in v39.

  • SLR

    Congrats for build 38’s release!

    Is there a way to force power saver on all the time? More power saver settings, like always activating while on battery would be appreciated

    • Aneta Reluga

      This feature is being still developed, so thanks for your feedback!

  • Laurent Bauer

    Hello, I didn’t think version 38 would come this fast !
    What a pleasant surprise.
    Wondered if Opera allowded desktop notifications for its extensions.
    Thanks in advance.

    • Mikolaj Boc

      Yes, we’ve been supporting desktop notifications for 2 years now.

      Plus, we support NATIVE notifications, not the custom ones, if available.

      • Laurent Bauer

        Thanks for answering.
        I installed Chrome Download extensions and Checker Plus for Gmail on Opera, works for sound notifications but not for desktop notifications.
        May be that’s for that reason…

        • Laurent Bauer

          Cool, I don’t know what happened but it works now ! Farewell, Google Chrome…
          Opera forever !

          • Mikolaj Boc

            Welcome onboard 🙂

          • Mikolaj Boc

            Also, please mind that if you are on Win8 or Win10, we respect the settings from the ‘Notifications’ section, so if you have Quiet Hours enabled or whatever that blocks the native toasts, you won’t receive any notifications at that time.

  • Joe438

    When using the mouse wheel icon to scroll and then when you use the mouse wheel button or left click to stop scrolling there’s a bit of lag. I hope I am being clear.

    • Aneta Reluga

      What is your operating system? Thanks.

      • Joe438

        Windows 7. Is there a larger version of your avatar? It looks cool 🙂

        I must retract my earlier statement. It may have been my imagination earlier.

        • Aneta Reluga

          Which statement exactly – the one about the avatar or the one about the scrolling lag? 🙂

          • Joe438

            I retract my statement about the scrolling.

            I am still quite interested in seeing a larger version of your avatar if that is possible. It seems to be half woman/half machine in a mostly red light giving off that evil overloard aura 😉 Very dystopian/sci-fi.

          • Aneta Reluga

            Indeed, it’s a vanity avatar made by me a while ago. Components used for the composite: a photo of myself from some time ago and the Terminator 3 poster, right part (yes, I was inspired – that poster was a good piece of work)
            Image manipulation: ArtRage + PS.
            Evil-ish aura: so much intended!
            A bit bigger version is here:
            I refuse to show the original size though – it would be all too much visible then how lame was the frame overlay. 🙂

          • Joe438

            Much appreciated! It did make me think of Terminator as well. I’m a big fan of the terminator franchise. I can understand not wanting to show the original size as that would cause it to lose some of its image quality.

            Thanks again 🙂

  • Jorge Barrera Castillo

    grande opera sin duda el hecho de seguir innovando, vuelve a las raices de este navegador, no lo cambio por ningun otro y ojala se vuelvan mas mejoras..saludos desde chile

  • Yan.

    Thanks for this amazing browser !
    We need a option for smooth scrolling.
    Smooth scrolling increase CPU usage = more power , more heat. Please give us a option to disable it. Thanks !!

  • Marko Koivuniemi

    I would love a flag which disables dragging tab to another window. It’s feature I never need but very often do accidentally.

  • How is the custom block list format? Just a list of sites in raw txt file?

    • Nekomajin43

      Easylist syntax.

    • Mikolaj Boc

      Url support incoming in 39.

  • nem

    excelent feature of saving battery

  • Yro

    Great version so far (at home only. at work, the problem was posted as bug report). Is that any plans to bring all these features (native ad-block, power saving) to smartphones too? This would be great..

  • Anar

    Always on for battery would be perfect, it’s a nuisance to have to enable it every time the browser is started. Otherwise excellent feature and looking forward to VPN in stable release .

    • Mikolaj Boc

      We are working on some enhancements and the one you mention is on the to-do list.

  • Dominionseraph

    Opera 38 breaks Hotmail. Thanks for wasting 3 hours of my life troubleshooting that nonsense.

    • Try holding shift and click on the page reload button (Might have a bad cache file) (ps Hotmail is also know as

      It is working fine for me

    • Leonardo Gomes

      Breaks how? It seems OK here.

      • Dominionseraph

        Instead of sending out, emails were getting stuck in Draft. (Emails go to Draft before going out.) Clearing the stuck email showed the Draft folder was FUBAR, giving various errors from the site, depending. (delete/send/edit)
        This persisted through several reboots and logins, and the log shows the first failed email was within minutes of Opera updating to 38.

        • Leonardo Gomes

          I’ve just made a teste here and could send a message from without any problems.

          Do you use any extensions?

          • Dominionseraph

            Just ublock.
            It was a very messy account with ~450 messages in the inbox and 250 drafts.

    Hi, I have a problem with the Scrolling in Ubuntu 16.04 laptop. When i search images in google, in the results page with all that thumbnails, if i put the pointer over a thumbnail and try to scroll with fingers, there is a lot of lag in the scrolling. The problem is not happening with mouse, only with two fingers scroll. It also happens in other websites.

  • Javier Bastardo

    Thank you team! I’m so happy with Opera lately, you’ve been my default browser on all my devices since quite sometime and the latest things you been doing are great.

  • Kaushik Patowary

    I’m still waiting for “load cached images” option. Please add this. Since you are so interested in improving browsing speeds, that should be next in line.

  • K. K. VinayKumar

    Battery saver should remember the user setting. It becomes annoying to turn it on every time we open the browser and many a times we forget to turn on the battery saver. Hence this feature kind of becomes useless when you don’t remember to turn it on every time you open the browser.

    • Nekomajin43


    • Kornelia

      Thanks for suggestion. I’ll forward it to battery team.

      • article10ECHR

        Could you also forward the suggestion to enable users to use battery saver when plugged in, for low powered devices or also to save power / heat in general? Maybe just call it power saver 😉 Is there an advanced option for this?

        • Aneta Reluga

          Actually it should be possible even now – the only thing is that this does not remember the setting after restart.

        • Shadess


    • Druplit

      I couldn’t agree more! Great job so far though, I think the battery saver is a great USP for Opera.

  • Сергей Рощин

    where is vpn?? adblock doesnt delete ads in Russia ((

    • Kornelia

      We’re still working on VPN feature to make it absolutely perfect. Please give us some more time. About adblock – can you give any example of sites where ads are not removed?

      • Сергей Рощин very many ads
        i use ad muncher – it block all ads and pop up and video sometimes

      • Pavol

        Kornelia, since Opera developers don’t want to spent their time to give users some freedom in customization of UI (positions of individual bars) and make them happy. Do you know if there is at least extension available which can move bookmark bar besides the address pane? So both, address pane and bookmarks are in the same line? Thank you

    • tu.iga

      You can find the VPN in the latest developer version

  • K. K. VinayKumar

    Please provide an option to change the menu name from “Menu” to “Opera” because I like “Opera” name more than just “Menu” name.

  • Dmitriy K.

    Anyone else experiencing screen flickering? Win10x64 here and it’s hard to use O38 bcoz of it: The page goes blank for 5-10sec and then goes back 🙁

    • Donovan

      Yeah, I’m having this issue too. Can’t seem to find a fix.

  • Jademarisa

    For me using Opera with a PC battery saving is of no consequence, so can’t tell anything about it. I know that as usual I’ll get backlash but I miss customization and a menu bar. When you get that Opera will become my browser again (I dropped for Firefox after Opera 15). Pity because it’s becoming fast, I’d love it to become usable again

    • Nekomajin43

      What do you want to use from the menu that you need a full menubar?

  • Dark Magician

    And did you stop developing mobile version, it’s still stuck on 36?

    • Leonardo Gomes

      I guess you would prefer to ask the mobile team.
      Anyway, there’s a beta 37.

  • Pelcom

    I have a very annoying problem. When I’m surfing by Google Maps, the scrolling is not soft, It’s always jumping when I move the position. I compare it to Chrome and the result is totally different. In Chrome is very soft. Please, fix it. My computer is a Macbook Pro 2014 13″ with magic mouse and Opera 38.

  • Pavel Aleksandrov

    There’s a small visual bug when making a video full screen (for example YouTube). The video visually stretches out past the outside of the monitor (I see it go into my other screen) and then snaps into place where it should be.

    • carpenter92

      It happens in Chrome as well, probably related to the Blink engine, Firefox’s fade-out-fade-in method hides it. (Or it doesnt even happen with the Gecko engine)

  • Michał Gołębiowski

    Just to confirm: NPAPI support is officially gone in this version, isn’t it?

    • Radek Rzepecki

      NPAPI is officially not supported since the last couple of versions.

      • Michał Gołębiowski

        There was still a flag for it up until this version so I thought it’s supported. 🙂

      • Aneta Reluga

        Does it persist for a longer time, or is it a shorter time lag?

        • I can reproduce this issue with these steps:
          1. Visit a website
          2. Click on a link
          3. Use the mouse gesture to go back
          4. See the issue
          5. One mouse click on the page
          6. Issue gone.

          Using the button on the top left to go back does not trigger the bug. Looks like it must be a mouse gesture.

    I’ve installed Opera 38 to C:UsersnameAppDataLocalProgramsOpera (W7x64) for a specific user but it doesn’t save the setting for it to be the default browser and keeps asking for it every time the user restarts the browser. Same when I tried to install it using admin rights this time to C:Program Files (x86)Opera
    Any ideas?

    update: a crazy bug, after setting the default browser as Google Chrome and trying it again with Opera it saves the setting.

    • Aneta Reluga

      Is it the ‘Current user’ installation?

      • xirit64

        Hi Aneta, yes.

          Ok, thanks. I’ll investigate on Monday morning most probably.

    Does the Opera Stable automatically use or import user profile files from Opera Dev, or a custom migration is needed?

    • Nekomajin43

      Manual migration.

    • Leonardo Gomes

      Each stream/channel uses its own profile folder.

    • Marcin Mitek

      Manual/custom migration of the profile is not recommended and not supported. You might end up with corrupted profile data. Of course it might also work well in 90% of cases 😉 But you don’t want to be in the remaining 10% 🙂

      The safe way to transfer your data between streams is syncing.

      • redfox

        The profile folder contains also extensions with their setting .. a lot of additional work to do, if everything should be rebuild from scratch. I think I try the migration first.

    Opera 38.0.2220.29 often crashes after downloads or opening tab menu. Just does not respond anymore.
    On Windows 10 | Surface Pro 3 on Insider Ring Fast & Surface Pro 4 on Regular Build | NOT on Desktop.
    Probably somehow related to using the Surface Pen. Also when turning off the pen cursor in Windows settings, I can no longer interact with Opera with the pen.

    • Any extensions added?

      We will have the ability to import adblock lists from online sources in v39. Until then, you can download any adblock list that follows the easylist syntax, and import it manually from your machine.

    • ShintoPlasm

      Another halfway solution I’m using at the moment: use both Opera’s adblocking feature and uBlock Origin, and disable EasyList and EasyPrivacy in uBO (i.e. use it for all other blocking lists currently not supported natively by Opera’s adblocker).

  • shooterboss

    Awesome job, guys. The battery saver feature is working great on my end. I’m going from 5 hours to 7 by turning it on.

    Also, pop-out video was something I’ve been wanting for a long time, though I wish I could change the size of the pop-out.

    Edit: Snap, didn’t realize I could drag the preview to make it bigger. Sorry bout that. Excellent job anyway.

    • Aneta Reluga

      Is dragging the pop out corners not working for you? Can you please try?

      • shooterboss

        Dragging the pop out corners works great. Thanks again.

    • proffibra

      Dragging by pinpointing corners works on Linux, but the problem with that window is it’s not managed by WM. Therefore it’s not possible to use usual, much more ergonomic way to resize windows on Linux: meta key + mouse-button (middle or right, depending on WM and user preferences).

  • Jose Diaz

    So I did some RAM testing on my surface pro 3 between chrome and opera with and without batt. saver. Both browsers have the same tabs open: a tab with sonyalpharumors open, another with digitaltrends and a 3rd tab with this article. Chrome is using ublock origin while opera uses its own ad blocker. I loaded those pages and let them rest for 3 minutes. Here are the results:

    Chrome: ~220.5MB
    Opera w/o battery saver: ~247.9MB
    Opera with batt. saver: ~274.7MB!!!!!

    The feature that is intended to make opera take less resources is actually taking even more. Even Opera without that option is taking more RAM than chrome, which is weird.

    • xirit64

      The RAM does not work the same way as a CPU does so concerning power saving what you have tested and your conclusion is pretty out of context (politely said 🙂 )

    • Shadess

      Ram usage doesn’t have much to do with battery usage.

    • jonidimo

      But you should test the time.

  • Dhamo

    please VPN ASAP.

    Also note, I’ve tried all opera VPN extensions, none of the extensions not compatible with “https” sites. All extensions blocks from opening those “https” sites like google,gmail etc.

  • Юлия

    You should auto disable smooth scroll when power saver is enabled. It’s not that smooth at 30fps, and you’d also save more power by doing so, less CPU usage.

      Thanks for the feedback!

    It seems like instant actions on are not working on opera 38.
    It wasn’t working even after disabeling all my extensions, while it was working fine on another browser, and since there were no problem before the update I guess it came with the 38 version.
    It’s not a big issue but still, those were really useful 🙁

    • Leonardo Gomes

      Try disabling the ad-blocker for that site.

      • Sen

        As I said in my previous post, I already tried disabling the extensions (including opera’s built-in ad-blocker)…..
        And it works perfectly fine in another browser with the same extensions.

        • Leonardo Gomes

          I was referring to Opera’s ad-blocker in case it was enabled.

    Another problem in fullscreen mode with the Esc button =(

    Description: If you open in fullscreen mode drop-down list on the website, and then press the Esc button, it closes the drop-down list + the browser will exit fullscreen mode

    Steps to reproduce:
    1. For example, open this forum:
    2. Go to fullscreen mode (F11)
    3. Open the drop-down list in the lower right corner:
    4. Press the Esc key

    Actual result: Pressing the Esc button will close the dropdown list + the browser will exit fullscreen mode

    Expected result: Should close only a drop-down list


  • Darklink88

    Very nice feature! Happy to see it in the stable channel. Is it possible to show some results from tests made on osx? Here Safari seems to be ahead of Opera in terms of battery usage.
    Think you!

  • MiniKiss

    Opera 38.0.2220.29 crashes regularly when I delete all data (select all items) in private mode, no mater if addons are enabled or disabled.

    It would be nice if you give users option to prefer h264 videos over vp9 on html5 video player sites. It would be better for slower computers and even for laptops batery saving since more devices support hardware decoding of h264 than vp9.

    About VPN: please give users option in options to decide if they want use VPN in private mode or not (in normal mode, just to go for site which is unaveable in their location and eventually log in to this site (cookies, etc.)). If they don’t want use VPN in private mode they would have the third “kind” of window (1-normal mode, 2-private mode, 3-VPN mode), and in other case (they want use VPN in private mode) they have 2 types of windows, like it is now.
    Also startup option -vpn would be useful to start browser strait in VPN mode, along combined (or not) with -private option.

  • Jose Diaz

    I have an issue with the opera battery saver on my surface pro 3. When changing tabs, the browser stops scrolling, either by touch or the type cover, but i can go to other tabs and menus. After about 20 seconds, the entire browser freezes and then, it either force restarts itself or the tabs separate themselves in new windows. After a couple of days battling it, I stopped using that feature until fixed.

      • Part of the issue is that Google screwed up some code ( would think this would break in Chrome and others, I wonder if Google is sending Opera broken code (I turned off ad blocker for Youtube gaming and Ghostery is not blocking anything there)), a work around to watch a youtube gaming is you have to right click and select open in new tab.

        Hello, thank you for your reply:

        – I didn’t report the bug through wizard (I posted similar comment on the previous blog post just to see if anybody else is having the same issue)
        – it is happening since the introduction of the feature
        – OS: Win7 x64

        I think it may be the problem on my end – I’ll try to figure it out.

        Thank you for your awesome work on browser – keep it up.
        I’ve managed to get all my family and friends to use Opera
        (mobile and desktop version so I’ll try to see if they have the same issue) and they are more than satisfied.

        Many websites fight ad-blockers by INTENTIONALLY breaking their functionality. Don’t allow websites do that – find an alternative. There is a lot of less-popular but better “internet speed testers”. Also note that speedtest encourages ISPs cheating by providing servers.

    Please add keyboard shortcuts for muting tabs. In Chrome for these purposes, I use a wonderful extension “Mute Tab Shortcuts”:

    In Firefox, for this purpose is using the keyboard shortcut Ctrl+M.:

    Need 3 hotkeys:
    – Mute/Unmute the selected tab
    – Mute/Unmute all audible tabs
    – Mute all audible tabs except current

    Dear Opera developers: Can you add support for Netflix video at 1080p resolution (or higher)? This could increase Opera share in browser market.
    _Chrome, Opera and Firefox support playback of Netflix movies in 720p resolution in Win7, Win8.1 & Win10. IE11 in Win7 support only 720p (it uses Silverlight 5).
    IE11 plays Netflix movies at resolution 1080p in Win8.1 and Win10. Edge in resolution 1080p or 4K in Win10.
    Adding 1080p or 4K in Opera would especially important for Win7 users (all browsers play Netflix video at 720p in Win7; there is no Netflix app for WIn7)
    Win7 is on 48% PCs and will be major Windows system for 5-10 years.
