The only reason why you should use FF over IE7 or any IE at that is vulnerability issues! IE is so open to hackers galore! Your ports are all open when you use the program and when a virus or trojan is created...guess what they base it around to attack? You guessed it, everyones default program Internet Explorer!! That is the ONLY reason why FF is better then IE (which is a dang good reason for me to use it)!!!
