X-Firefox

X-Firefox is an official portable version of the popular Mozilla Firefox web browser aimed specifically at users who either don't want to clutter their computer's OS registry or have a need to run the software directly from external storage devices (even though it can also be run from the hard-drive).

X-Firefox is offered by winPenPack, an interesting project that offers people some of the most well-renowned open-source software made portable.

X-Firefox offers 100% of the functions found in the normal, installer version of Mozilla Firefox. This means that users will benefit from everything that the normal Firefox offers, including its latest engine (Gecko), latest GUI, and latest features including tabbed browsing, a download manager, support for live bookmarking, private browsing, location-aware browsing, Firefox sync, support for add-ons, and so forth.

Deploying X-Firefox (be it on your computer on any compatible storage device) is quite straightforward. At first, the browser starts in "silent" mode. This means that the files will be downloaded in the /Bin folder, and a .ini file will also be created. Once the process is completed, the setup will automatically remove all the files from the folders in question.

Last but not least, please note that X-Firefox cannot run while a normal instance of Firefox is running on any given computer.

To conclude, X-Firefox is a very good option for users who love Firefox and either want to run on the go, directly from external sources (external hard-drives, USB flash drives, etc.), or simply do not want to deal with any registry changes on their OSes. By employing the services of X-Firefox, users can be sure that are running the latest versions of Firefox in portable form.
