As somebody who deals with computers all day (IT consultant), Firefox is the ONLY way to go. IE has so many security issues it'* unbelievable. I had a customer that wanted a pop-up blocker installed on her computer....so I installed Firefox, and haven't had a single complaint since then.
well main reason I had to switch to mozilla is just because of the spyware that was flooding in, but I still need to use IE for some pages.
The new IE looks like a CLONE of firefox, with the upper right hand search bar and the tabbed browsing, but the back/forward buttons are at the very top, and I dont see a way to fix that yet, so when you hit back button twice your drunken finger double clicks on the icon to close the program
