Firefox vs IE
There have been TONS of Firefox vs. Internet Explorer comparisons, but few such as the one written on BBspot. Here is an example of one of the topics covered in the comparison:
Names
Internet Explorer - Microsoft leaves no doubt what their products are. If they made toilet paper it would be called Butt Wiper. Internet Explorer isn't a bad name, but it's not spectacular.
Firefox - On the other end of the spectrum, the name Firefox gives no clue to what it is. Could be a car? 80s video game? Lame comic book superhero? Flaming dish at a wild game restaurant? A browser would probably be your last guess. No matter, it is a much cooler name than the utilitarian Internet Explorer.
Advantage - Firefox
