      Not having any issues with videos playing on the site with or without Opera's adblocker in Opera 128.0.5807.77 on Windows 11 23H2 for what it's worth.

        @misterrr I'm glad the issue doesn't exist in version 127.

        The problematic version 128 was available only for a few days. We can't simply force users to roll back by having them reinstall it.
        If you download Opera today, it will be version 127.

        Thanks to everyone for all the details and for investigating together 💪

          @burnout426 Yes, but I think that in order to be able to play the videos with adblocker on, you have to add the site to exceptions. In Opera 127 that was not necessary.

            @Mlipka Ok. I hope that in the next Opera update the problem will be solved. I will keep you informed.

            Thank you all!

              @misterrr I didn't have to in 128.0.5807.77 for what it's worth.

                @burnout426 So, to summarize, until now we have three behaviours in Opera 128:

                • @leocg: with ad blocker on: video doesn't even show, its space is blank. With ad blocker off, I got a Media Element Error: Format Error message
                • @burnout426: video ok / no error
                • @misterrr: with adblocker on (and no site added to exceptions): instead of video I get a black frame with no video / with adblocker off (or site added to exceptions): I get no error, the video plays but with unwanted behaviour

                Strange...

                  Are these issues are related in a way, as they're affecting something in the resolving of DNS? 🤷🏼

                  These problems also only appeared with version 128, making it nearly unusable for me.

                    I can't cofirm if issues are connected but highly recommend switching to 127.

                    128 has been withdrawn.

                    If you download fresh installer, it will update to 127.

                      @Mlipka I'm afraid, it didn't. It brought me: Opera 128.0.5807.77

                        @Mlipka In order to avoid a fresh install, and to update automatically to all users, it would be possible to publish an update that in fact is the last working version (127), obviously with a version number greater than the current non-working version?

                          Ok, we got into little version chaos, let me clarify.

                          1. Problematic 128 was released at the beginning of the march, it was withdrawn after a day but some people got it.

                          2. During the rest of the March there were several new versions of 128 with fixes. Latest this Friday (13.03.2026).

                          3. Yesterday (18.03.2026), we release version 129.

                          🙃

                          Apologies for confusion.

                          Anyway, please update browser manually to 129, if it didn't automatically yet, and check reported issues.

                            @Mlipka Just updated to the new version:

                            From:
                            Versiune Opera One: 128.0.5807.77
                            Versiune Chromium: 144.0.7559.173

                            To:
                            Versiune Opera One: 129.0.5823.15
                            Versiune Chromium: 145.0.7632.117

                            Unfortunately nothing changed. The problem is still here: black screen instead of video (with adblocker enabled) and unwanted behaviour (with adblocker enabled and site added to exceptions).

                            I think this 129 version should also be withdrawn as soon as possible to avoid spreading and replaced with 127 working version., until the problems will be solved.

                                We struggle to reproduce this problem.
                                Can you make sure you don't have any other AdBlocker that might we still working?

                                What could help us is a screenshot of DevTools when you try to load the videos.

                                  @Mlipka No, I don't have any other AdBlocker (excepting Opera AdBlocker).

                                  Example for https://stirileprotv.ro/stiri/doctor-de-bine/combinatiile-de-alimente-care-iti-potenteaza-nutrientii-si-aduc-beneficii-mai-mari-decat-suplimentele-alimentare.html

                                  Console with adblocker on and no exceptions added (video does not load):

                                  console_1.png

                                  Console with adblocker on and website added to exceptions (video is loaded):

                                  console_2.png

                                  I see that I can't attach har file (for network) or console log file.

                                    Can you check in the settings if EasyList Cookie List is enabled? If yes, can you disable it and try again?

                                        Just updated to the new version:

                                        From:
                                        Versiune Opera One: 129.0.5823.15
                                        Versiune Chromium: 145.0.7632.117

                                        To:
                                        Versiune Opera One: 129.0.5823.28
                                        Versiune Chromium: 145.0.7632.117

                                        Unfortunately nothing changed. The problem is still here: black screen instead of video (with adblocker enabled) and unwanted behaviour (with adblocker enabled and site added to exceptions).

                                        I don't understand why non-working versions are published, instead of maintaining in place the last 127 working version, until the problems will be solved.

                                          Hey @misterrr,

                                          This issue seems very specific, and we haven’t received reports of it affecting other users on a large scale. We tested the links you provided but were unable to reproduce the problem. Therefore, there’s no need to roll back to a previous version.

                                          There was a problematic version 128 that had multiple issues and wasn’t stable, which was withdrawn the next day. All versions released after that have been stable.

                                          If you haven’t done so already, please create a bug report following this guide: https://forums.opera.com/topic/88353/report-your-bug-here

                                          Simply include this thread in the description, and the team will review it.

                                            I did some further investigation into my settings in the adblocker / exceptions / lists area because I think that's where the problem is:

                                            block.png

                                            I found something that makes a small difference if I remove it. It's a list I added in 2024 but I haven't had any problems with it so far:

                                            fanboy.png

                                            If I remove this list, the videos load when the page loads (the video frame is no longer black without the video) and can be started, but the other problems (which I think are related to Opera's behavior) remain:

                                            • when the page loads, the videos start by themselves, without me giving the "play" command
                                            • when the page loads, the videos are on "mute" and must be put on "unmute"
                                            • when scrolling down the page, when the video clip goes off screen, a pop-up appears with the clip in the lower right corner of the page, without me asking for this
                                            • when scrolling down the page, when the video clip goes off screen, a pop-up appears with the clip in the lower right corner of the page, which restarts even if the clip in its main frame was stopped, without me asking for this

                                            I mention that all the settings for detached video and for Video Popout | Picture-in-picture video are disabled, but Opera does not apply these settings:

                                            video.png

                                            These are unwanted behaviors that should not exist.

                                            I would like the videos to be stopped on page load (and not start on their own even if I scroll the page) and to be unmuted. Now it is the opposite.
