I have switched every PC I have to Firefox. With IE, I used AD Aware every day and cleaned 30 to 50 items. With Firefox, my Ad Aware works about as much as Pres Bush and when I do use Ad Aware I find only 6 to 10 items.
I have noticed it is a bit slower than IE, and have changed some settings but still seems a bit slower. I would love to hear how to speed Firefox up a bit more--anyone please post those fixes here?

No popups for me either, but I have noticed that I see errors in code--even on big sites like Yahoo with Firefox that I wouldnt have seen with IE.
