Well from my POV I think firefox is better because of these reasons:

1. I.E doesn't work on some sites or either make the website sloppy from what the original source is.
2. Firefox is more efficient and faster than I.e because of all the toolbars that you can download to make life more easier.
3. From firefox 3.0 you can just type the name of the company or the title and you will get your website in the address bar in no time.
