Firefox Portable

One slick way to bring your browsing environment with you everywhere you go is to use a portable version of Firefox that runs from USB drive. Thanks to the determined efforts of developer John Haller, you can download and install a free, customized version of Firefox 2.0, and install it on your thumb drive with a couple of clicks. Some limitations apply?not every extension or plugin will install or work correctly with Firefox Portable, and Java not at all. Haller explains it all on his website, where he offers a whole suite of portable applications, including Mozilla Foundation's Thunderbird e-mail program
