One thing that others have not noted, is that is it open source, unlike Internet Asploder. You can get the source of Firefox, chop it into Sushi, roll it in rice and seaweed, and call it SushiFox. You just have to credit the original. Internet Exploder, on the other hand, is a closed, locked, stored, in a safe, guarded by 300 security guards type secret. Unless you somehow obtain the source, illegally, that is, or you work at Microsoft, you don't have any chances to edit it, to make it better. Also, even with Windows updates, IE is still a ways more vulnerable than Firefox, due to the fact that it is a more widely known browser. You can use what you wish. I for example, also use OpenOffice. But enough about that.
