Portable Firefox v1.0 (USB Drive-Friendly) Portable Firefox is a fully functional package of Firefox 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). This is an unofficial package (Windows-only for now). It is an official build, but has been modified and a specialized launcher added to make extensions portable. No warranty is expressed or implied.
