This is in response to all the people that keep saying, "Yeah, but I've downloaded firefox like 5 times myself". On my system, and thousands of others, firefox hasn't even been "downloaded" once. It comes packaged by my distribution (debian). So, all those debian/ubuntu/gentoo/etc users out there that have firefox packaged by their distro are not really being counted at all, unless I'm missing something about how they come to these figures. I wonder how many debian/ubuntu users alone there are that have never manually downloaded the browser and are not being counted.
