After a break without a developer release last week, today we are delivering to you for testing few new features.

Faster startup

Starting the browser should be very fast. However, until now, if you had many tabs open last session, the browser would start loading all of them at the same time. This could mean slowing down the browser. With Opera 41 we’re working on optimizing browser startup time with the most recent active tab and pinned tabs being prioritized for startup, while background tabs will be loaded with decreased priority. We are working on benchmarks results, to be shared soon. Meanwhile, let us know whether you can feel the snappy startup!

Battery saving improvements

When using battery saving mode, Opera now detects which video codec can be hardware accelerated and tries to choose that codec when doing video conferencing via WebRTC (this includes services such as Google Hangouts). This should save a lot of CPU and battery for our laptop-using video-conferencing hobnobbers out there! And even if Opera can’t find a hardware-accelerated codec, it’ll now also try to limit the pixel count when in battery saving mode to reduce CPU usage if possible.

The test has been made on a MacBook Air 6,2 (Intel Core i7 1.7GHz) running OS X 10.11, running one side of a video conference on AppRTC from full battery (100%) until the battery has been fully drained.

Battery saver comparison

Hardware acceleration for Video Popout

Video popup so far has been handled by the software, which translated into extensive CPU usage. On low end devices that could lead into general system slowdown.
Now we are introducing hardware acceleration support for Video Popout. This should greatly limit the need for CPU support and free your PC resources to other things, while you watch your favorites movies.

Sync enhancements

We are rolling out some security enhancements, and we will share more details in the future. For now be advised that if you use passphrase, you will be able sync only between latest desktop clients (Opera Desktop 41).

Popular searches

We have added experimental support to popular searches below the search box in Speed Dial. . The idea is to have one-click access to trending searches. So far the backend is manually fed, so while we’re working on it, you might find more of what we think is trending, than what the rest of the world is searching for.

Personal news updates

There are multiple changes in personal news, here are the most visible ones:

  • Onboarding redesigned and aligned with catalog.
  • Added history navigation, now you can go back to previous view.
  • Due to limited interest, News on SD removed.
  • More web feed related fixes, including image loading.
  • Search got even more powerful: No need to include http:// prefix when entering site’s name.
  • More feeds found during discovery process

To discover more take personal news for a test drive or check changelog.

Known issues

  • Autoupdate for Windows USB standalone installations does not work. To update these, please download and install the package manually.
  • We are not releasing Windows 64-bit builds.
  • It is not possible to enable VPN with a clean profile. It is being tracked as DNA-56872 and we are working on a reliable solution.
  • With #media-detachable-view-hwaccelerated enabled, closing the popout and selecting a new movie makes the popout open again.
  • Speed dial extensions are not added on Windows

Please check out full changelog for details.

    Thank you…………

  • iPristy


    Bring the 40 first, that would be great, it’s 3 months in the oven now.

    Testing 41 anyway…

    Will you fix connecting VPN on Linux it’s still doesn’t work.

    • BK

      Summer time stabilization is a bit longer.

  • L33t4opera

    Hi Błażej, thanks for the update and fixes 😉

    – opera:flags#power-save-mode-webrtc-video-codecs
    If battery saver is enabled, VP8/VP9 codecs have a lower priority in WebRTC communication than H.264. Requires "Battery saver" and "VP8/VP9 suppression" to be enabled, and support for hardware accelerated decoding of H.264.

    – opera:flags#power-save-mode-webrtc-video-pixel-limit
    If battery saver is enabled, use a lower maximum pixel-number when encoding a WebRTC video stream; thus the video resolution is decreased and less cpu is used.

    – opera:flags#lazy-session-loading-default-enabled
    Enables the "Delay loading of background tabs" setting by default.

    – opera:flags#speed-dial-search-suggestions
    Adds search suggestions below the Speed Dial search box. You can toggle it in (advanced) Settings > Browser > Start page > Show popular searches.

    – opera:flags#enable-asm-webassembly
    Validate Asm.js when "use asm" is present and then convert to WebAssembly.

    – opera:flags#passive-event-listeners-due-to-fling
    Forces touchstart, and first touchmove per scroll event listeners during fling to be treated as passive.

    – opera:flags#browser-task-scheduler
    Enables the browser task scheduler to dispatch tasks instead of the existing worker pools. The browser task scheduler will only be used if variation parameters are available.

    – opera:flags#enable-feature-policy
    Enable granting and removing access to features through the Feature-Policy HTTP header.

    Removed flags: #media-detachable-view-phase2, #news-on-startpage, #news-stacking-layout, #personal-news, #personalized-news-start-page, #start-page-search-improvements, and #turbo-for-news-on-startpage.

  • Vohmyanin Sergey Vasilevich

    Where is x64 Windows build?

    • Aneta Reluga

      In “Known issues”.

      • Vohmyanin Sergey Vasilevich

        It is there for at least 5 builds. I consider moving to Chrome or even Vivaldi when they add sync feature

        • Aneta Reluga

          Yes, I know. My personal apologies for this, but then again, I’m just the messenger here. 🙁

          • DaZung

            Please consider posting some additional information on the status of the x64 build. Is it on low priority because you have diverted all resources to other projects deemed more important? Is some large code refactoring (why) going on? Is something very broken (what) and you are having trouble fixing?

            I understand x64 is experimental and not supported and that you are not at liberty to post internal Opera information but for me at least having some info to “chew on” would go a long way to ease my x64 withdrawal symptoms.

          • Leonardo Gomes

            I would guess it’s a building issue.

    • L33t4opera

      Hi, in the meantime (while you’re waiting for the 64-bit version), you can use the 32-bit version on the 64-bit Windows. Simply install it in the 64-bit (current) installation folder. The profile should be intact, but before you perform the installation, please make its copy, and if something goes wrong, you can restore it from the copy.

      • Vohmyanin Sergey Vasilevich

        ADB devices debug not working in developer tools, but in Vivaldi works awesome. This issue is from 30x builds

  • Ralf Brinkmann

    Hi BK! “It is not possible to enable VPN with a clean profile” – are you sure? Because I can not connect with VPN and nanana1 said, that a clean profile solved his problem. 🙂 It is not too important for me, because I’m not a registered whistleblower, but it would be nice to find a solution. For all the others.

    • BK

      Hi Ralf. This is being worked on, should be fixed by next week 🙂

      • Ralf Brinkmann


  • João Gonçalves

    The Facebook slowness is still not solved. Takes a lot of time to load facebook feed and some other sites as well.

    • Leonardo Gomes

      What OS? Facebook loads very quickly here on Windows 10.

      • João Gonçalves

        Windows 10. It’s better than last build, but still not as fast as previous builds.

        • Ralf Brinkmann

          Yes, I can confirm this behaviour here on my W10x64. And when I go from one open TAB to the next one (after having started Opera), I see first an empty, white page and THEN Opera starts to load the content. Everything very leisurely and unhurried.

    • mb

      Thought this was an ISP issue, but I have/had 2 PCs here with the same issue. 10 x64: one normal, one insider.

  • Ralf Brinkmann

    The problem, that Opera (or Chromium) doesn’t remember the position of a page when reloading it, is unfortunately still there.

  • NoName

    Startup is way faster now. Thanks!

    But the shortcut bug in the address bar is still there (activating shortcuts when editing URL).

    • BK

      Great to hear ! Happy browsing.

  • Kai Ockendorf

    Thank you! Startup is really faster, but when will we ever get rid of this “busy circle” on the mouse pointer after startup? It’s a bit disturbing! W10x64

    • BK

      Nice ! Thanks for testing.
      I’m not sure about the busy status, will check.

      • Kai Ockendorf

        Thanks checking 🙂

  • DavidMay

    I still really see a use case for Personal News on Speed Dial for me personally and for a wider audience. Having personal news directly on SD has two distinct advantages. a) It is immediately available when opening a new tab (no second click required b) Enables me to dynamically choose between my SD sites, suggested sites, and any news item I find interesting.

    It is hard to argue against low usage numbers, but I argue that this was also due to the awareness of this feature and how it relates to the new personal news feature. I had the impression that news on SD were deprecated since you started working on the separate personal news feature – they seemed like two completely separate entities (e.g., evident through the two totally different source settings menus for both). I think there is still potential in having a configurable personal news directly on Speed Dial (maybe even in addition to the separate tab).

    • Thanks for your input. Such feedback is always valuable for us when deciding how to steer feature development.

      • Sazarac

        It would be nice to be able to toggle it as a choice. I already miss it. 🙁

  • 1timecomment

    Will there ever be an x64 update for Windows?

    • Leonardo Gomes

      At some point, I guess.

  • Der Herr Nick

    Can you please fix the backspace in address bar issue?
    Pretty please?!

  • Ralf Brinkmann

    Facebook in this Opera Developer is sooo r e l a x i n g . But sorry, I don’t have this time. I’m back at the Beta. Whoosh! Is that fast.

    • João Gonçalves

      Not only in Facebook. Several other sites take time and time to load.

  • Marek

    The startup seems really quick, but I had an issue when after I closed Opera with no tabs open, after launching it again, there was a random tab from my history opened.

  • x a

    Hmm, there is nothing really new to lazy-session-loading, is it? It’s the thing those of us, who enabled it, use for over a year…

    • Leonardo Gomes

      I guess now it’s enabled by default.

    • Arjan van Leeuwen

      Yes, there are some differences :). Although the idea is the same – lazily load some tabs – there are now some heuristics to load more than just the active tab on startup.

      Tabs are loaded based on the priority they get. These tabs always get loaded directly:
      – the active tab
      – tabs on which the user has enabled desktop notifications
      – pinned tabs

      These tabs get loaded with increased priority:
      – tabs visually placed around the active tab

      We load up to 10 tabs on startup, with maximum 3 tabs being loaded in parallel to limit strain on the system.

      After that background tabs are loaded when you click them as before.

  • Momfer1

    >>> We are not releasing Windows 64-bit builds.<<<


    • MarkG54321

      Big question, even more so, when Google release Chromium/ Blink 64bit builds. Quite clearly, Opera broke something….

    • Leonardo Gomes

      Probably for the same reason they haven’t been releasing x64 builds since a while.

    • Luis Amaral

      No win64 versions means no new installation on my system. I will be checking out alternative browsers soon.

  • Marko Koivuniemi

    This build seems snappier (so I can again use Developer as my main browser) – but there is interesting transparency bug in Facebook chat. I has happened twice – when opening chat window there were stripe that shows facebook page below. I have never earlier seen this before. I try to find a way to reproduce it. (OS X 10.11.6 /Macbook Pro Early 2015)

    • Kornelia

      Thanks, I’ve reported this issue in our database, DNA-56919

      • Marko Koivuniemi

        I have seen it happen again in OS X but not at all in my Windows 10 64-bit machine. I don’t remember do I have any additional flags enabled – I will check those later.

  • Ghirahim

    Something went wrong because Opera became incredibly sluggish on some sites, 4chan for example. I just tried MS Edge and it works perfectly. The last two builds are awful.

    • Leonardo Gomes

      I’ve just tried 4chan and it seemed OK here.

  • Erick

    Now pinned tabs are loading after startup, but I prefer to load only if I click them. I can’t revert this behavior?

    Edit: ok, I disabled opera://flags/#extended-lazy-session-loading and everything is fine now.

    • I don’t really understand how loading all tabs gradually is going to help with the startup process or performance quality if it uses more resource than before!!

      • Leonardo Gomes

        By default all opened tabs would start loading at the same time during the start up process.
        Loading them gradually prevents it to happen and makes Opera to start up faster.

  • yigido

    What the heck is “popular search”
    Big nooooooooooooo!
    Are there any option to disable it?

    • L33t4opera

      Hi, you can disable it in Settings > Browser > Start page > Show popular searches (to be able to see this option, make sure that you have enabled “Show advanced settings” in Browser > Advanced settings).

    • Agree. Why would one care for popular searches?

      • yigido

        Yes, I do not care that “What Chinese guys searching or what the other Opera users searches?” How Opera achieve thsi? Guys Open your eyes, Opera will collect your search terms “by default”…. This option must be disabled by default. If anyone love this feature, they can enable on settings. Please consider this… Please do not make Opera a chinese shiny browser!!!

  • iG0Lka

    Please take the feature to open the selected link in a NEW tab page.
    On some pages , such as forums games , links are present in the form of text , ie they can not open the mouse . It is necessary to highlight the text and links in the menu on the right button to select – “Go to web address ” .
    As a result of the opening takes place in the same window . It is very uncomfortable!!!

    • Laga Mahesa

      Seconded! This is why I never use that open and do it manually instead.

    • DMCA
      • iG0Lka

        many thanks!

    • ManOnTheBorder

      I agree, this should be default behaviour, I don’t understand why they haven’t changed that yet.

    • Rafał Chłodnicki

      I don’t have opinion on what should be the default action, but the fact that this function doesn’t respect modifier keys is a bug. If not that, you would be able to ctrl+shift+click to open in a new tab.

  • Laga Mahesa

    Is Reddit Enhancement Suite (RES) not working for anyone else?

  • I don’t understand why news feature was removed from the speed dial. Who the hell wants to sit and configure their news? Why not to just visit the sites that they want to see instead? I really liked the fact that I could see news and sometimes scroll through it right from the speed dial. Now I will probably never use it.

    • Michal

      Agreed. I just tried without news feed on SD for a while to see how I liked the other one, but the thing is, I always forget to check it. When I have it on the speed dial, I don’t need to click anywhere else, I just have it on the main page. Please don’t remove it.

  • Kirby green

    Download button at the top right doesn’t work.
    Nothing happens when I click.

    • _artem_

      mine’s working

    • doogie

      I have the same problem. Not only the download button is affected, but the battery saver and VPN also. Synchronization works fine though…

      • Aneta Reluga

        On which operating system are you both? Thanks.

        • doogie

          Both my private laptop and office desktop run Win 10 Pro x64. One has these issues, one doesn’t.

          • Aneta Reluga

            Uh. This will be hard to investigate then, but thanks, we’ll keep an eye on it.

        • Kirby green

          The one has the problem using Windows 10 Education x64 Build 14915.1000 of windows Insider.
          My other PC running Windows 10 pro x64 works fine.
          Both are opera ver 41.0.2340.0

  • iYuzver

    When you plan to release the stable 40th version? I want to see how to display the smilies!

  • Didn’t we use to have this startup feature many moons ago? Or is it my idea?

  • marcassin

    I get the message “The VPN is temporarily unavailable.” Opera takes care of the problem. OSX 10.11.6

  • Is there an option to disable the video popout completly?

    • L33t4opera

      Hi Pavel, Settings > Websites > Video pop out, untick the checkbox on the left of “Enable video pop out”.

  • Tratsing

    Settings -> Browser -> Synchronisation -> Advanced configuration
    Clicking on ,,Advanced configuration” won’t open nothing.

    • BK

      Are you logged in to sync?

      • Tratsing

        Yes, I am.

    • Leonardo Gomes

      Works here. What OS? Windows 10 here if it matters.

      • Tratsing

        Windows 10 me too.
        Now I can see it but just after enabling it, I couldn’t open.After browser restart, I managed to open it.

  • doogie

    Posted this in the .2329 comments yesterday, still have the same issue in this build:

    On my personal laptop, the VPN, Downloads and Battery-saver menus in the top bar appear to be broken (Synchronization works fine). The buttons themselves work (battery changer changes color, download button shows progress and finished downloads, buttons are responsive to mouse-over and click events) but the pop-up menu doesn’t appear.

    I tried uninstalling and reinstalling, but the issue remains. Meanwhile, everything works perfectly on my office desktop…

    • Aneta Reluga

      By chance, does your laptop have touch screen? (I am unable to reproduce and trying for possible reasons)

      • doogie

        No, it doesn’t. I tried several methods myself – uninstalled everything, reinstalled the last x86 build, menus broken. Unistalled and reinstalled the last x64 build, menus worked fine, after upgrading to this build, menus are broken again… BTW – the Tab menu doesn’t work either

      • doogie

        Forgot to tell you – in the meantime i figured out the cause of the issue. My laptop has two GPUs, an on-board Intel and discrete Nvidia. Regardless of the GPU settings, the Opera menus don’t work if hardware acceleration is enabled. If HWA is off, the menus work as expected. I imagine only very few Opera users experience this, but might still be worth looking into, or at least post a warning once the HWA checkbox is ticked…

  • Nekomajin43

    Will you implement an RSS source page action feature or not?

    • Aneta Reluga

      This feature is being evaluated, but no promises whatsoever. Sorry.

      • Nekomajin43

        Can you specify what are the things against it?

        What is the point of the RSS reader, if I can not detect whether is a source on the page? I know the clean GUI mantra, but it should be optional, of course.

    • I think you might have something to test out with upcoming developer update 😉

      • Nekomajin43

        I hope so! Thanks for the info.

  • Kirby green

    Search pop-up doesn’t appear. (Win 10 Education)
    I don’t remember exactly since when but I had this problem on several versions.

    • Leonardo Gomes

      And it’s enabled?

      • Kirby green

        Yes, it is.

    • Kirby green

      I found I can click and search when I select the text and click above the text.
      So the pop up feature is working but it’s not visible.

    • Kirby green

      I found this problem appear only when I enable the hardware acceleration.

  • g d

    No News on SD I am aghast, one of the best things about any browser i’ve ever seen.
    Personal news cramped and dull, no background or sized tiles, tree on side needs to hide.

    But wait after editing installation_status.xml back to 41.0.2329.0 i suddenly have both?? it rocks….but not for long???

    • Thanks for your comment. Please note that personal news offer better functionality, not only you can select the sources that you find interesting and omit the ones you don’t like, mix languages and categories but also add custom web feeds. Non of that was available in News on SD. You have two distinct view for your sources: timeline and stacked (similar to layout used by News on SD).

      • g d

        I agree choice is better, but can you leave option to display news on SD as there is more room and thematic background.
        If not can “Personal News” selection tree have Hide/Unhide with Thematic background like SD?

      • Ariane Lu

        Any progress about stop keyboard input issue after use DevTools > Mobile Emulator ?

  • g d

    Please place option to retain News on SD with old tiles and background theme.

  • modemjunkie

    Noticing a lot of page crashes in this 41.0.2340.0 . Can’t isolate the cause.

  • Vague Rant

    I’m not able to add any custom RSS feeds in this version; I can add them from the presets, but when entering any feed of my own choosing (e.g. http://www.metacritic.com/rss/games/3ds ), Opera simply sits on “Searching for custom feed” for eternity. I’ve confirmed in the Flags that #rss-in-personal-news is set to “Default (enabled)” and tried toggling it a few times and rebooting just to be sure. Any advice?

    • Leonardo Gomes

      I’ve just tried that link here and Opera quickly found the news source.

      Do you use any extension?

      • Vague Rant

        I do use a couple of extensions, but disabling them all doesn’t change the behavior of Personal News for me, unfortunately.

        EDIT: Watching the behavior of the Network tab in the debugger thing (Ctrl+Shift+C), nothing is even recorded when I paste an RSS feed into the field, implying (I think?) that no request is even being made.

        • Leonardo Gomes

          Do you use Turbo or the VPN? What about firewall, anti-virus or antimalware?

          • Vague Rant

            Turbo and VPN off. I tried briefly disabling firewall and antivirus, but no change in behavior there either, sadly.

          • Leonardo Gomes

            Have you tried with a clean profile?

  • A. R.

    Add Tab stacking!

    • AMEN!!!!!

      Popular searches, though? Yeah, that’s something we all need 😀

  • Tratsing

    After keeping certain forum pages opened for a long time, then Opera is getting slower on these forum sites. If I open different web page in a new tab, then browsing on it is much faster than on tabs, that have a forum sites opened for a long time.
    This has occured on me with last two developer builds. Before it was no problem.

    • SiMcarD

      same problem here

  • Avery Chou

    It seems like the video pop up is not functioning recently on my win 10 computer, could it be a result of the newly added hardware acceleration mentioned above?

    • Leonardo Gomes

      What exactly is not working? Video pop-out works fine here.

      • Avery Chou

        For me,the pop in/pop out button responded to clicking, but there’s no window pop out. Re activating the function did not fix it.

  • L33t4opera

    New build – Opera developer 41.0.2349.0 😉
    This time together with the 64-bit version for Windows.

  • satainkara

    OPERA pleaseeeee pleaseee make SCROLLING like in opera 35 or say what setting set in SmoothScroll 1.5.6 (((((((((((( i like new opera but not like new scrolling (((

  • disqus_gG0WuLwfSZ

    Please revert the ‘delay loading of background tabs’ setting to the way it used to be. I don’t want my pages to load until I view them!!
