Didn’t they already support all addons a few years ago, and then limited it to the hand-picked ones?

Yeah, sure, it’s always the same story:

1. Chrome adds a shitty anti-user “feature”
2. Firefox users say “no come to firefox we don’t have that!”
3. 3 months pass
4. Firefox adds the same “feature” because it’s the standard now!!

I’m a Firefox user myself but I really hope something new comes along that actually cares about its users
