Firefox is good but I don't know why sometimes when I have many sites opened Firefox often disappear from my screen.
IE can suck my *** through a straw. its slow, annoying, stupid, a windows browser(there is is right there!), and you think they could have improved after so many years but you know windows(thier os never improved)
If a site doesn't support firefox I say f' it, 60% of people use Firefox now, those people have to learn that. I only use IE to test out sites I'm working on to make sure it works in all browsers.
Firefox, and the reason is simple: There are less exploits for Firefox compared to IE.Also, I'm already using a Microjunk ( read Micro$oft or just Microsoft ) application ( Windows ). Another one ( IE ) would be too much for me
