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).
In fact I’ve just downloaded it, and installed it on my 128MB USB stick.
I downloaded the newest “Beta” version from this link.
A nice new feature to add to my bag. How about you?
