In case this is something of a deal breaker for someone, please try setting up a VM and playing around with Linux. You don’t need to install it on your main system, or try dual booting it, but load up a VM and give it a shot. You don’t have to stick with it and if you don’t like it or it doesn’t work for you or it’s too confusing or whatever, that’s fine. At least you can say that you gave it a shot.

Reporting back, you were absolutely correct. Hardware acceleration was turned back on, and turning it off fixed the problem.

I’ll give it a shot. I don’t use flatpaks, but I think I’ve already disabled hardware acceleration for a previous issue? I’ll report back once I’ve checked/tried it out.

Nope, just uBlock. If I disable uBlock before loading the page everything works fine as well, so I’m pretty sure it’s uBlock.

But I’m on Linux (openSuse Tumbleweed) and have had some interesting “distro specific” bugs in recent months, so I’m chalking it up to “my OS + Firefox” and not “uBlock”

Mine isn’t working flawlessly with this exact set up, but it’s just forcing me to refresh the page every time I load a new video. Still no ads.
