IE has tabs as well... I'm using IE on the desktop (that I hardly ever use) and FF on my laptop. I don't really have a preference between the two browsers, but I LOVE some of the FF plug-ins. (Really, how did I live without InFormEnter and SnapLinks? )
FireFox ... FireFox only specially when it comes to fast browsing ... am really wondering when i hear anyone still using Internet Explorer ...ooohhhhh
