don't even start arguing about the Web advertising stuff that Mozilla pulled recently, yes it sucks but it's way less bad than what Google is doing with Chrome. If you want to use a random fork of Firefox over it I don't care and that won't stop me from telling "regular people" to just use Firefox, non-computer touchers shouldn't daily drive a random fork of a web browser imo okbyeeee
Been a Firefox user for years - a big part of it is the extremely OP Multi-Account Containers extension that allows using different tabs to access the same website under different accounts without having to do that whole logout-login shuffle, as well as keeping separate containers for anti-tracking purposes.
Container tabs are the one Firefox feature I'm baffled that no other browsers (to my knowledge) copied yet. No I don't want a whole-ass profile, I just want to log into my private Twitter/Cohost account in a separate tab real quick.
