i recently made the switch from mozilla to firefox out of curiosity. can't say i'm satisfied. they both display the same way, obviously, but firefox seems really slow.
it takes a good 40 seconds to load my home page, google, in a new window when the app is running in the background. it is also noticeably slower while browsing.
oh well, i guess it's back to mozilla--too bad, i liked the way bookmarks were handled in firefox.
