maybe there is problem with your setup? because i do use youtube on firefox without a problem (+ublock and +vpn) and i don't see advertisement. though, of course my main gate to youtube is FreeTube.

Probably some form of A/B testing. I used to say the same thing, but specific channels and specific live-streams will now die every 30 seconds using FF+uBlock. I found they appear to do testing on channels they do not like such as those that complain about YT's policy and other channels for reasons I shall not speak of here.

I also use ublock + vpn. Do a quick Google search for "reddit + firefox + youtube not working", you'll see that strings are getting posted much more frequently over the past six months.

youtube on firefox works just fine for me. can you describe this means it’s bricked?

Videos play for 10 seconds then stop loading, forced reduced quality, and just generally buggy in several different ways. Many Reddit strings with tons of other people having similar issues.

I use youtube over 30 times a day in firefox the passed year without issue.

I'm a constant firefox youtube user, hours a day at least, for years, I've had no problems at all. Is this actual FUD?
