It's funny that you say most people use IE because for a while over 70% of the hits that I got to my website used FF and less used IE. But I just had a look at it now and it seems to have become around 51/49 (favour FF)
Here are my stats
MS Internet Explorer 78869 84.2 %
Firefox 8225 8.7 %
Unknown 1772 1.8 %
Links 1622 1.7 %
Opera 1314 1.4 %
