I’m not. First of all, people disagreeing are more likely to respond than people agreeing. Furthermore, there are a lot of people using FF, not because FF is so good, but because they don’t want to use IE. They want to fight the “Microsoft Monopoly”. And yes, these are not the most intelligent people, since there are, and have been, other choices.

Fictional discussion with FFF (FireFox Fanatic):

“Why do you use FireFox?”
“Because IE sucks!”
“Ok, but WHY do you use FF?”
“It has tabbed browsing!”
“But IE also has tabbed browsing.”
“FF had it first!”
“No, Opera had it first, so why do you us FF???”

etc. etc.
