The more bullshit like this I read about YouTube the more I despite them. I already use GrayJay on mobile and I'm using ublock Origin + ublock Matrix on Librewolf to control cookie usage on desktop. So far I've been able escape the video player block by clearing cache.
I'm just waiting for the day they "force" me onto another frontend.
Then your uBlock Origin filters aren't working properly. See this thread for instructions on how to purge and update your filters to block YouTube's ads and YouTube's adblocker blocker.
Those 3 or 4 times may have been after Google had updated their anti-adblocking stuff and before uBlock Origin had updated their anti-anti-adblocking stuff.
Also, do you have any other adblockers installed? Does your browser have its own adblocker? Either of those can cause interference with stuff like this.
It sort of does for me. I used ublock to block the popup and the overlay that prevents you from using the site. Sometimes a video will stop playing for a moment, but it resumes as soon as I hit play.
im using librewolf too.
i keep seeing the adblocker active warning instead of a video, in the video-box on youtube
Plays just fine in private window though..
