Fire Fox is a non-Microsoft browser. It is used for basically the same thing as is IE. If your happy with the interface from AOL, I don't see the need to change. I don't like AOL as it limits the screen and slows down my dial up screen change speed. I do think it probably gives u extra protection from malware. I switched to fire fox because I was having issues with IE. I have stuck with it because of the built in Add Blocker, isn't cracked as much as IE and don't want to depend on MS for everything.
