Otherwise, a new window of your local install will be launched. Additionally, be sure you've closed any local copies of Firefox and that they've finished shutting down. DO NOT launch the firefox.exe file directly, as this will create a profile on your hard drive or use an existing one. To use Firefox on your drive, launch it with the PortableFirefox.exe file in the firefox directory. It will create a 'firefox' directory and all the requisite directories underneath. To install, just download the ZIP and unzip it to the root directory of your USB drive. It will also work from a CDRW drive (in packet mode), ZIP drives, external hard drives, some MP3 players, flash RAM cards and more.

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. Portable Firefox is a fully functional package of Firefox optimized for use on a USB key drive. We don't believe in fake/misleading download buttons and tricks.
