Portable Firefox is a fully functional package of the Mozilla Firefox web browser optimized for use on a USB key drive. It has some specially-selected optimizations to make it perform faster and extend the life of your USB key as well as a specialized launcher that will allow most of your favorite extensions to work as you switch computers.
It will also work from a CDRW drive (in packet mode), ZIP drives, external hard drives, some MP3 players, flash RAM cards and more (Note: It will not run from read-only media like a CD-R, but Portable Firefox Live will)
Very interesting, specially that you have to backup always your profile directory only, to do an update, or burn it on a CDROM … etc. There is a number of modifications and additional options that you can find in the website in addition to the launcher. Portable Firefox Launcher 1.1.0 is already included in the main download file.
