He's right as far as Firefox. I have a U3 Smartdrive Micro and I downloaded Firefox on there because I hate the schools shitty internet service and I got countless addons without screwing Firefox.

However, you must be careful what addons you get. There was one I got and I found out that it makes me have to uninstall and reinstall Firefox on my drive.

BTW, I find scrapbook to be a useful addon because you can get your favorite games off of any site (almost) and play them on any computer, even without internet. Very useful.
