Portable Firefox allows you to carry your whole web browser along with all your bookmarks and extensions with you on an iPod, USB thumbdrive, portable hard drive or any other portable media. You can plug it right into any Windows computer and use it just like you would on your own. It is a repackaged version of the popular Mozilla Firefox browser designed with portability in mind, so it has all the same great features of Firefox, but there's nothing to install.
