Getting back on track. I just yesterday had an experience on why Firefox > IE.
My site had some really strange issues that were completely unexplained, firefox, etc displayed it PERFECTLY.
Text was randomly disappearing. the backgrounds were wiping clean as you scrolled the page. It was so freaky.
Anyways, only IE did this. after some research, i found that MS's retarded browser requires you to do a certain "hack" to set some sizes on some divs to 1% (which in normal browsers which display this correctly, fux it, so you have to hide it from all bug IE with a hack)
conclusion. IE sucks, Firefox wins
here's a wonderful link outlining the gayness of IE.
