Not every PC has the software you like to use installed on it. Sometimes, another person’s PC or public computer may block you from installing any software on it. For example, if you would like to use Firefox browser but the PC only has Internet Explorer browser installed. Then, you should check out this portable application.

If you use Firefox 3.5 browser, you can also try Mozilla Firefox 3.5 Portable Edition.

It is an integral part of the PortableApps.com Suit. You can import and export the add-ons together with their settings like your own installed Firefox using Firefox Environment Backup Extension. However, this software is currently compatible with Windows Operating System only. You don’t have to install this software, just simply extract it to a folder and start the executable file to use it directly on your portable drive that connected through the USB drive to your PC. You can download the Portable version of Firefox 3.5 at portableapps.com.
