      @kiquja Click on the UBO icon on the extension bar (assuming it is visible at the right top corner of the browser, then look for triple gear icon which is for settings. If the uBlock Origin icon is not visible then hold down the CTRL and SHIFT keys then press E on the keyboard. Then locate UBO on the extension list and then click on the Options under UBO. Go through the options under the "Settings" and the "Filters Lists" tabs.

      Most importantly, keep uBlock Origin up to date. major browser update can break its auto update function especially is there is a major update to the browser and it is not compatible with the current version of uBO.

      Another fact Opera users need to keep in mind is, unlike Brave or Firefox, most other mainstream browsers including Opera are using Chromium engine which no thanks to Google, has been slowly but surely getting pushed with Manifest V3 rules the last year so eventually uBO will not work right or at all with Chromium based browsers like Opera/Edge/Chrome/Vivaldi. What you need to do is, swap uBlock Origin with uBlock Origin Lite which is supported by Manifest V3. This version of uBlock is not quite as configurable or effective as the uBO but it will not likely to have any issues either.

      My current primary browser is Brave and I am using uBlock Origin Lite and no issues on YouTube.

          Youtube detects it now. Is there a way to fix this now or we have to wait for an update?

            You don't really have a lot of choice but to wait, but if you want a more interesting project to eliminate YT ads I saw a post on the forum of OpenWrt, it is an open source router firmware based on Linux, they were looking to eliminate in the router so they never get to your device.

            There appear to be several different solutions relying on 3rd party sites for code and testing.

                @fckopera If you really want an old version go to github.com/gorhill/uBlock and manually download 1.64.0 (or whatever other version you want) by going to the releases section and downloading it.
                then unzip it in file explorer.
                then go to opera://extensions and turn on developer mode (top right) and then press "unpack extension" and open the unzipped folder but you need to go one folder deeper, (if you don't, it won't load)

                I would like to uptick and thank you for that, apparently I lack reputation.

                  Ublock Origin is STILL not working for me

                  I noticed a grey box comes out when I click on the pinned uBlock icon

                  2025-09-09-13-16 uBlock Origin Grey Box.png

                  Also I noticed but I discovered this error in Dev mode

                  Uncaught (in promise) TypeError: Cannot read property 'split' of undefined

                  I have googled it and see the error discussed on coding sites but that is as easy as learning Chinese for me.

                  I copied the code in the error from Dev mode but this forum has a limit of 5000 characters so you can read it below

                      @kacperopera: Uninstall it, clear cache and cookies, restart opera, reinstall. It fixes it, at least temporarily. Needed to do it again about a week later, but worth it honestly.

                        You shouldn't have to uninstall a browser unless you are having error when launching the browser or when trying to update it.

                        Just about all browser data that matters will be in the %AppData% and %LocalAppData% folders. Some use just the \AppData\Local\ (ie. MSEdge, Chrome, Brave) and some browsers use both the \AppData\Local\ and \AppData\Roaming\ folders (Opera, Firefox, Waterfox).
                        Browser folder under \Local folder typically contains static data and maybe the session data where \Roaming folder will have bulk of the data and most importantly, user, extensions and other profile specific data.

                        If a user is experience problems with their browser on a specific site, best to make sure their browser is up-to-date, then start a "private" aka "incognito" session which will effectively disable all extensions, cookies and dynamic cache for that session. Check to see if the site is still having issues or not. If not, you know cache, cookies and/or extensions are likely the culprit. If still having issues, then more than likely a more complex issue inside the user browser profile to be the culprit.

                        If that is the case, I'd simply close the browser in question, then rename the browser folder to something that starts with OLD_. So, if using Opera browser, rename both "Opera Software" folder under \AppData\Local and \AppData\Roaming so they read:
                        "C:\Users\youruser\AppData\Local\OLD_Opera Software" and "C:\Users\youruser\AppData\Roaming\OLD_Opera Software"
                        Then fire up Opera and visit the site again to see if you still have the issue or not.

                        When you uninstall a browser, the browser's user data folder(s) under \AppData\ are not related. If renaming the folders didn't fix the issue, then uninstalling the browser from the system would make sense as well as hiding the existing data folders as mentioned above.

                          @turcoloco I apologize, I wasn't clear enough. You uninstall ublock origin, not opera. My bad for my lack of clarity.

                            Oh, no worries. Yes, with uBlock Origin, I had to do that once in a long while even though the auto update was selected. You could tell this is the problem when all of a sudden ads would no longer be blocked on YouTube.
