looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )
here is an article in hacker news since i'm sure they can explain this to you better than i.
and also some github docs
I personally switch between IceCat and LibreWolf occasionally which I believe will cut out this feature, but if Chrome implements this feature, expect Firefox to follow suit within a couple of months once usage ramps up on platforms like Nflx etc
I will not back down, as the fight for a free internet is important to me, but it is not important to Firefox, before everything else, Firefox wants higher userbase to earn more money.
Yes, Mozilla has been slowly taken over, so the time where I could stick to stock Firefox is drawing to a close. I think a useful community supported fork will emerge by that time.
The tor browser itself should just do ehat you want (without connecting to tor itself)
Yes, that is also an option I'm aware of.
