Firefox is a great browser and Mozilla is a (generally) great organization. It's my daily driver on all my devices (except my TV ha), it's fast and has great plugins that also work in mobile. Philosophically I'm very much a "root for the underdog" type of person so it makes me happy that way, too. Only very rarely (every few months) am I forced to use Chrome for a site - and in my view, that's a huge ding on the site devs, not on Firefox.
It's strange hearing reports of "scroll lag" in the other comments. It's possible I'm just lucky. Or there's a misconfiguration somewhere in their setup that Chrome somehow avoids.
It's true that I still mostly use Chrome for webdev - I've become more used to it's (excellent) dev tools, even though Firefox and Firebug started that whole trend. It feels very right to separate my "user browser" from my "dev browser" in this way!
