I can't really talk since I use Mozilla suite for my main browser, but I did use Firefox before that so I have some experience. The real reason that a lot of people are still using IE is that it is bundled into the OS, it is relatively simple to use and works with every website. Firefox and other Gecko-based browsers have trouble supporting sites that aren't standarized. I think that Firefox is more feature-rich and more personalizeable with its plugin support. I think that in the long run Firefox will be a replacement for IE, but that that time is still a while off.

PS: I switch to the suite because it has the features I need.
