Another Firefox fan here!! And one of my favorite features is that you can have it save all your open Tabs/windows so that if you're in the middle of something - or just have several pages you visit often - they open back up the next time you're on! I usually have ACOT, Facebook (PackRat at least) and a few others. Especially now that I'm job hunting, if I find something interesting but don't have time to complete the application until the next day, no problem, no writing down the address so I can find it again, it's awesome! (And yes, it's much more reliable than IE, and loads pages with graphics tons faster!!)
