Yep, what the other ladies said - more secure, faster...and also it reads website code better so pages display correctly. Probably not a big deal if you're not running your own website, but it's SO annoying to get your webcode done, put it up and have it look right in FF but IE screws it up and you have to go insert INCORRECT code to fix IE's issues. LOL! Web developers believe that EVERYONE should be using FF...it's an all around better web browser...IE is made by Microsoft, therefore is faulty.
