Go Mozilla. Firefox all the way. I don't even use IE anymore after finding out about tabbed browsing. Opera has that annoying ad on top, and it's a bit weird. Mozilla is good for Linux Users. IE is not W3C-compliant, so it's not that good. However, I think that of all browsers. Safari is the best. It has an oh-so-pretty GUI, is as secure as Firefox, and has tabbed browsing. Apple should port Safari to PC, but, of course, that's never going to happen. Apple wants people to buy Apples. I bet the next version of IE will have tabbed browsing, since all these other browsers have tabbed browsing.
