This developer update brings you more Reborn and ad block improvements, as well as some security and performance changes.

Reborn project continues

In today’s version, we added a menu button which will allow you to log out from your sidebar communicator without needing to visit the communicator’s website. From the menu you can also mute your communicator notifications.

Also, Opera now brings you a new pop-up when adding bookmarks, which includes the “Finished” button. This option gives a clearer way of adding bookmarks for users who missed the confirmation that a new website was already added to the bookmark folder.

For Windows 7 user we are working on a big update.

Ad block anniversary improvements

Last week, Opera’s native ad block celebrated its first anniversary. Now, this feature has been given a refresh with some new, handy options.

Opera automatically reloads a page when toggling ad blocking on or off for that page. It’s especially useful if you want to quickly flip the switch and it gives you much more control and comfort while browsing with ad blocker.

Also, we have added some important changes to the block list management. Now, you have control over which block lists are loaded. Easylist and EasyPrivacy are turned on by default.

Other lists, including regional and custom lists, can now be managed through the “Manage Lists…” dialog. Let us know if there are any other lists that you would find beneficial.

Apart from that, Opera now offers support for more advanced CSS selectors, which help you block more ads.

Known issues:

  • Changed configurations are not reflected instantly – a reload is needed
  • Unticking all lists doesn’t work as expected – turn off ad blocker to disable any blocking

Performance and security changes

H.264 video works in Windows 8.x again and it now has the same hardware support as Windows 7 and Windows 10, both given in the last developer release.

Opera adds in-form warnings for sensitive fields when the top-level page is not HTTPS. Whenever you start filling in your password or credit card number on a page, which is not HTTPS, the warning will appear.

That’s all this week. Stay tuned.

  • Very nice updates! Looking forward to this release!

  • Nekomajin43

    Will you implement element blocking via context menu?

  • jojoPL1987

    Why Developer wersion don’t have option “Show in bookmarks” in heart menu? New stable version too dont’ have this in future?

    • Leonardo Gomes

      It was probably removed.

    • Herr Pietrus

      Personally I think it was useless 🙂

      • jojoPL1987

        I like function this button.

        • L33t4opera

          Hi, for now (it might change in the future), you can bring it back by disabling opera:flags#improved-heart-popup.

  • Internal adblock – the most expected feature.

  • L33t4opera

    Hi Maciej, thanks for the update, and fixes, it’s quite nice build 😉

    One minor bug, or feature for some of us: assign Alt+M for Manage Bookmarks, go to YouTube page, and start the video playback, press Alt+M, and you should see what happens - it doesn't happen, when you assign Ctrl+M, or just M (in this case, you have to click somewhere outside the video box, and not on the search box of course), to make it works.

    One new flag: opera:flags#web-payments.
    Enable Web Payments API integration, a JavaScript API for merchants.

  • Vux777

    for anyone wondering…
    clicking “Done” button on heart popup menu is the same as clicking out side
    if you expected for bookmark to be added only AFTER you click on “Done” button, that’s not the case
    bookmark is added immediately after you click heart in address bar

    • Nekomajin43

      It’s a good solution, I think. Straight-forward for noobs and comfortable for everyone else.

    • Herr Pietrus

      And that’s great!
      I was afraid that I’ll have to click something in order to add a site to the bookmarks instead of “clicking outside”. 🙂

      • Nekomajin43

        Uh-oh, we think a new feature is good as is. Something went wrong. 🙂

  • Sunny Fofoja

    Where the opera 44 is stable you said it will be soon 7 days have passed and usually you will release the release in 3-5 days as the new version of Google Chrome is released

    • Leonardo Gomes

      ‘Soon’ is something very subjective. One month may be soon and one week may not be.

    • redfox

      The O44RC has so many important bugs that it will be unwise to release it into Stable channel.

  • I Looooooooove Opera

  • albert71292

    The last couple of Developer releases, login at doesn’t stick, and the login at doesn’t stay logged in between visits. Works fine in the stable version.

  • Hetai-Na

    Please add option for enable acceptable ads.

  • Mateusz

    Since i moved to Opera 38 from chrome i visit this blog like every week to see what you guys prepare for me next. As for now IMHO Opera is fastest developing internet browser with improovments and new features every version. Keep it up. 🙂

    • Kornelia


  • kj

    I use selfsigned cert for apache web srv, from this build even if it’s installed in trusted root/trusted publishers it keeps me asking if I want to continue anyway… quite annoying.

  • oldq

    Vimeo still does not work

    • albert71292

      Works here.

    • Frederik

      Works for me. Not even a problem with the video pop out.

    • Rafał Wrzesiński

      Same problem with Opera’s adblock

      • oldq

        Google chrome showed this and other videos on the vimeo. The opera is not …
        The problem was solved by updating the driver of the video card nvidia

    • Works for me.

  • Cryio

    v45 looks quite nice. Can anyone bring me up to speed with the features/improvements v44 will bring?

    • Kornelia

      It will be clear very soon 🙂

  • Herr Pietrus

    It’s good to hear that you’re preparing something for Windows 7 users 🙂 I hope that also UI on Windows 10 will be polished.

    • Kornelia

      We’re not going anywhere. Stay tuned.

  • Łukasz Janik

    jeszcze prosze poprawic vpn, bo, niektore strony sie nie wczytuja.

    • Kornelia

      English please.

      • Łukasz Janik

        nie umie. jak nie sktualizujecie polskiego bloga, to pisze tutaj po polsku

  • firuz_u7

    AdBlocker needs the ability to block the ad element on the page manually, and there will not be need for other blockers

    • Der Herr Nick


    • Kornelia

      We hear you and we’re not leaving any suggestion without discussion 🙂

      • firuz_u7

        Thank you for not forgetting us. I look forward to these opportunities

    • Luis A. Rosario

      sometime ago I suggested this option,it was very usefull on presto based web browsers.

    • Is there anything in the other blockers that you would find essential to make the switch?

  • Slavic

    Security improvement is very important!
    Thanks for warning that login/password fields are not HTTPS. However, this can be improved even more. First, a user may receive additional warning if HTTPS certificate used in the login field is not the same as certificate of the main page. Second, another warning may be shown if HTTPS is based on the free issued certificate like Let’s Encrypt, which doesn’t have any additional fields in the Subject besides CN = domain_name. This becomes a serious problem nowadays, when the swindlers use such free certificates on the fake bank webpages in attempt to convince the user that it’s legal. Please consider such improvements.

    • Thanks for indicating that! Security is important for us.

  • Dany Gee

    In today’s update I really appreciate finished button in new bookmark popup. Lack of it confused me few times back in the days.

    • oldq

      Button that does nothing – it’s very valuable …

      • Well it closes the popup in expected manner. It’s appreciated by some and not needed by the others 🙂

        • Stefan Ivanović

          Well, it serves no purpose at all, actually, as the page is bookmarked instantaneously on hart click. It would make sense if page is not saved to bookmarks until “Done” button is clicked. Ctrl+D (as a very intensional stretch-your-two-fingers action) makes sense to be an instant saver to bookmarks, but the button-click procedure does not.

  • Hetai-Na

    Images in do not show in search results.

    • kraju

      It’s because you have Adblock turned on, try to turn it off – then it works.

      • Hetai-Na

        Yes, but I think adblocker should not cause the problem.

        • Leonardo Gomes

          90% of the time the problems are caused by the list.

        • Ariane Lu

          It no third-part list enabled, report it at here:

    • Strange indeed. There seem to be quite a lot of loading problems. I can see missing images in Safari and Chrome as well. Is it the first time you get this issue?

  • Hetai-Na

    Can you add option to refine search in Find Bar? Just like Edge or Firefox. Even Vivaldi have this. I miss this sooo much….

    • Caleb

      That would be nice.

      • Caleb

        At least you can use CTRL + F to find things on the page.

        • Leonardo Gomes

          This is how things ever worked. 🙂

    • Leonardo Gomes

      Refine how?

      • Caleb

        I think he means build it in to the UI.

        • Leonardo Gomes

          How it would be related to refine the search?

      • Hetai-Na

        I mean “Whole Word”, and “Match Case” check boxes. Firefox has it. I really miss this in Opera.

  • Caleb

    I can’t wait until they apply these features to the stable edition!

  • Predator2104

    Installing this build over older settings will make the browser to open tens of windows continuously in a single shot. It saturates the memory and causes the PC to be non responsive. I wasn’t able to stop the process from popping up in the task manager so the only solution was to log out and to totally remove this new build.

    On windows 10 64bit / 16gb ram / i5 4460

    • Leonardo Gomes

      Updating from previous build caused no issues here.

  • Crash to update from previous build (Opera sent the crash report)

    macOS 10.12.3

    • Kornelia

      We can see this crash too. Anyway, it’s all fine after it’s updated. We will see what’s going on.

      • I see it on and off with the 3 different streams

  • Humuhumu Nukunuku Apua’a

    A “reader” mode, such as Maxthon’s or Vivaldi’s, should be a standard feature of any browser. People with poor eyesight, especially seniors, ought to have the option not only to enlarge text (which Opera already does) but also to set contrast and to de-clutter a page (take out distracting, unnecessary elements such as images and ads).

    I’m hoping that this enhancement will be implemented before I’m 70. 😉

    • Ariane Lu

      I like this feature, but it’s really difficult to capture right text from website, non-standard code, or anti-robot feature, need a lot of rules and manual maintain

      • Humuhumu Nukunuku Apua’a

        It doesn’t have to be perfect or full-fledged. For now, it just has to be useful. Seniors just need to be able to read without straining their eyes.

  • Ariane Lu

    This address should NOT redirect to HTTP, or it may hijack by somebody and users who live in China was unable to download without a proxy

    • Leonardo Gomes

      At least here it doesn’t redirect.

      • Ariane Lu

        Maybe fixed after this comment? I have install Opera for some friends, and all failed without proxy

  • Kozak Mak

    pls add separators for bookmarks

    • Can you elaborate how would you like them to look like? Simple mockup would help:)

      • Kozak Mak


  • Marc

    Are there any plans in the future to add the tab-stacking feature? It’d fit nicely into this whole Reborn project, don’t you think? 🙂

  • Jaran Flaath

    Unable to get the Messenger panel to close after it has been opened. Have to click the new menu and “Hide panel” – shortcut doesnt work either. On Ubuntu 14.04.

    • Kornelia

      We’re aware of this issue and it’s reported internally. Our devs are working on this.

  • patkoscsaba

    Interesting. I already saw the security warning on my Linux machine which was not yet updated to this build… Is this some server side magic?

    • Kornelia

      Security warning? Screenshot please.

      • patkoscsaba

        I meant the warning regarding sending password over non encrypted HTTP forms. The one from your article above (last image)

    • No magic, and good catch:) It was not mentioned last week, but I think it is still worth talking about it.

  • roman61rus

    Still no opportunity to change speed-dial tiles to/for transparent custom made logo. Facebook with transparent background for example, when you can make it in photoshop and store it in a special folder in opera profile.

  • ͕͗F͕͕͗͗i͕͕͗͗n͕͕͗͗d͕͕͗͗u͕͕͗͗s͕͗

    “Easylist and EasyPrivacy are turned on by default.”

    Nope. I have not a single list there. Nothing. All empty. Using the portable version. Whats wrong?

    Edit: Ok. Have to restart (why?!) opera after enabled it. Now it’s there. But it’s slower than uBlock and that makes it useless for me.

    • Ralf Brinkmann

      I had the same problem and can confirm it.
      Operax64 portable installation

  • BlB

    Dear devs could you add a wire communicator since I think that its secure nature is valuable.
    Also I’d like to ask you what is happened with the option for external bookmark saving – is it still under development or is enough mature to be included in the stable channel?

  • Ghirahim

    “An error occurred while checking for updates”.

  • Kai Ockendorf

    Thank you for the hard work improving my favorite browser!:) The new improvements according to the adblock feature are great but unfortunately not enough for my daily browsing! But nevertheless a great start!! What really bothers me are ads (20-30 seconds) before a video starts! Ublock is doing a good job here:

    would love if Opera’s adblocker could do the same! Or does anyone have an idea which filter list I can add so that the video starts immediately??

    W10x64, O45x64

  • Dmitry Kirin

    Wow, it’s already a year that native block has been there. How time flies.

  • Stefan Ivanović

    I constantly keep getting very unexpected zoom-ins on web pages that I zoomed more than 100%. After “Refresh” it rescales to what it was previously and than zoom-in again. Very strange, there were no problems with previous Developer updates with this. I’ll try tomorrow at work if bug persist there as well.

    Edit: it seems to be extension bug.

    And, once AGAIN (people asked for this like 5000 times) make pinning tabs permanent with “Open on start page” startup preference, not with “Continue where I left off” only. Or at least, make it an optional preference. P.L.E.A.S.E.

  • Stefan Ivanović

    Tonight I am in mood for ideas, so lets make another one: Right click on link (or page) with document like pdf/doc/xls/jpeg/etc. opens context menu with send to/save to option to save the content to OneDrive/GoogleDrive/Dropbox/etc. to a folder named eg. Opera saves. All major cloud storage services provide this feature within their APIs, just need to have sign in option in Preferences for the service. Yet another thing that would make the best browser even “bestter” 🙂

    • Kornelia

      Thanks for suggestion.

  • jojoPL1987

    Pin left sidebar must by black? Why if I don’t used dark theme?

  • Vlad T

    What about auto-hiding sidebar and access them by moving mouse to the left side?
    And what about something like automatic reader mode in mobile versions? I mean hiding tabs and address bar while scrolling down a page.
    Consider these suggestions, please 🙂

    • Kornelia

      We will. Thanks.

    • SteUeRunG

      Opera 12’s sidebar which you could open by clicking on a thin edge leftsides was one of my favorite features back then. Hope it returns sometime.

  • swagnoodle

    Still just as ugly and the messenger apps are nothing but bloat. I really dread this redesign

  • Andrey

    Not working version for me, after update @usb x86 & x64 and fresh install @usb x86 i see only

    Show developer menu – not working.

      Hi, please make an update to the latest Opera developer build – 45.0.2545.0. It should help 🙂

  • Regnas
  • Regnas

    Hello, can you add a faster way of enable and disable the sidebar? An option to check/uncheck in the main menu or in the right click menu would be great, instead of open a new tab/speed dial just to do this… It’s a must..

    Thank you..

    • L33t4opera

      Hi, you can add a keyboard shortcut to toggle it in opera:settings/configureCommands > Show sidebar 😉

      • Regnas

        Thanks, but a quick keyboardless access would be better imho… 🙂

  • Max

    Something is not good with this build. In task manager you can see that commit mem. is over 4 GiB!

  • L33t4opera

    New build – Opera developer 45.0.2545.0 😉

    • Ralf Brinkmann

      ONE minute! 😀

      • L33t4opera

        Hi Ralf, ok! the next truffles are all yours 😉

          When I’m at home!

            Sorry, I was on tour! 🙂

  • armel

    Is there a way to completely remove the sidebar from the speed dial? I do not want it there at all. Even when it is unpinned there is space there I would like removed

    • Leonardo Gomes

      Nope, you can’t remove the navigation toolbar.

  • Mr.Ice

    Can you whitelist youtube channels like with other ad blockers? (I don’t know where else to ask this.)

  • Dorota

    How can I disable Welcome to Opera tab which show during first run?I need to change it in config / settings file.
