I am evaluating FF right now, I have always been a die hard IE fan, but I have noticed that both of them have their good and bad points. So far I haven't had any trouble with Spyware or Viruses from either one of them. So I say go for which ever one you like, neither of them have a real WOW factor that sets them apart anyways. I mean tabbed browsing for FF, and ActiveX for IE, big frigging deal. They both do the same thing, they find and display webpages.
