Mozilla is a hopelessly corrupt organization at this point. At any point they could block support from uBlock Origin working correctly. They still have all their Google money, so they won't be forced to make any real changes.
I have been on Librewolf for years. I use it on my personal machine and work machine. I know it's downstream and dependent on Mozilla/Gecko, but it's privacy aware and tries to strip out all their garbage.
LadyBird is our real hope now, not Servo. I hate all the slander levied against the lead LadyBird dev. He's an amazing individual who has overcome horrific drug addiction that almost destroyed his family. I try a LadyBird build every few months and it's pretty amazing how much work they've done.
