I don't understand the downvotes. In the current market of the Chromium and Firefox duopoly the only real options we have are forks that remove the greedy features. Ladybird is not ready yet.
You currently have no other choice but to use Librewolf, Helium, or one of the other Firefox or Chromium forks if you want to minimise support for Mozilla and Google.
Exactly. I have heard a teacher at my college say he's switched to Firefox to get away from Chrome, however he is clearly not in the know as he has Adblock Plus installed in Chrome on his work machine instead of uBlock Origin.
