All Firefox addons are currently disabled for all users globally because of an expired certificate somewhere in the chain. Oops.
This is an awkward day for anyone who has ever convinced a less privacy-savvy friend to switch to Firefox from a browser that was probably working perfectly well for them in the first place.
User notatoad on Hacker News sums up my thoughts nicely:
there’s plenty of reasons to be “with” firefox still, but you shouldn’t need reasons other than it’s the best browser. when it starts requiring loyalty to be a user, that’s a big problem.
