i like all three, and i use all three,but i keep coming back to safari.
it isn’t fancy but it works well.
camino is a good, basic, fast browser, but hangs on me more than the other two, tho it feels and respond more mac-like than firefox.
safari doesn’t have all the bells and whistles of firefox (tho it has more than most people realize), but i am also convinced that people who talk all the time about those add-ons rarely use many of them anyway.
when i use my gmail notifier to access an email, all i have to do to go froom that one email to the inbox on safari is click the inbox button, while firefox makes me take extra steps…little quirks like that (not recognizing when a pop-up is window related or not) keep me coming back to safari.
i have tried to like firefox, using it as default for a week or two everytime a new version comes out, but i still end up back at safari. and i am looking forward to the leopard version.
