Honestly though, I've found that Firefox runs nicely and is less prone to pick up nasties from the web than IE. Plus, I like the tabbed browsing.
It ain't all roses though, Java runs slooow as hell, if at all, through Firefox for me. So, I launch IE if I wanna play in the Arcade here. I also have trouble w/ signing on to some larger Corporate websites w/ Firefox, for example AT&T wireless or Verizon.
Oh, and I have to use IE when the kid wants to watch videos from Nickjr. Needs Windows Media player 10. Go figure.
Oh and I noticed something today. At work we have this amazingly shitty computer that defies death despite it's amazing age. I installed FF on it today and to my surprise it ran FF better than IE and FF rendered pages MUCH faster aswell. Interesting me thinks.
