Everyone is using Firefox and laughing at internet explorer, but I just don't see how they are different, is there anything that firefox has that IE doesn't?
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.
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
