How is Firefox better than Internet Explorer?

Simple. The processing rate and capacity for cookies is much larger. Also, applications can be used on Firefox such as pop-up blockers and spam filters for your E-mail and social networking.

Rockmelt still beats all.

I'll tell you some things firefox has that IE doesn't: less viruses, faster speed, better setup. Although if you ask me google chrome beats even firefox in those categories, plus the customability in chrome is fantastic. Basically: screw firefox and IE, go chrome
