I play and work on an online game (check the sig guys for the link if ya wanna try it) Basically because of modern standards of security ect ect it's hard to configure the downloadable image pack (whilst unnecessary, it speeds the game up some) therefore I have to be able to tweak my browser settings, thankfully Fire Fox have an addon called ChromEdit Plus which even on Vista makes tweaking the necessary file a doddle. Therefore I use FF2 still I haven't gone to the beta because if I do I've heard the compatability runs out with the game image pack. Though whenever I try uploading photos to my facebook/myspace/livejournal the browser suffers a catastrophic crash so for those I tend to go on IE7 and use that.
