Firefox has been proven to be better. The only thing is that when I go to my friend's piczo sites, Firefox doesn't show as much of his HTML codes as IE does. But my favorite browser is Safari, yes, you can get Safari on a PC, and it's great. (Except for Runescape, but I don't play anymore, so I could care less).
yeah, its just not right for some people, not me though, i think its great. But then some people like apple macs too. they're just happy with second best
FireFox - Faster - (no argument here, it is actually built into the browser in the way it deals with different codecs) Safer - Not only are most viruses written with IE in mind but because of the open source nature of firefox pretty much all buffer overflow issues have been sorted out NOT to mention being able to get more security related plugins. Choice - You have thousands of different plug ins that work with firefox, you also have the choice to make your own quite easily if you know some basic programming.
