Firefox does not use ActiveX, so you more often than not will not get spyware, as ActiveX is normally what Spyware and Malware attacks. That, and the aforementioned tabbed browsing, the built in pop up blocker, the great password manager... IE is alright, I have few quirks with it but I'm not going to sit here and tell you that I hate it because it is MS, that would be ignorant. But Firefox is an all around better browser. I mean, look at Tyler's avatar. I havent seen any with the little E eating the fox via packman style. Thats goota tell you soemthing.
