A portable web browser open source

Free Download

Your rating: not submitted

X-Firefox is a portable variant of Mozilla Firefox (registered trademark of the Mozilla Foundation) developed by using the unaltered official binary downloaded from, in accord with the "Mozilla Trademark Policy". X-Firefox includes Mozilla Firefox in its round setup form into the LibMozillaFirefoxsetup_en directory. At first use, directly and in "silent" mode, will be started the setup, extracting and moving all application files into the originally empty Bin folder, and preparing the accurate .ini file. At the end of installation, the setup file will be deleted from Lib folder.

This application copies all the options discovered in Mozilla Firefox, so do not anticipate to find anything more or less. Unfortunately, you cannot use X-Firefox while an instance of the original, installed Firefox is functioning.

While X-Firefox is active, the PC uses the same normal load of system CPU and memory, just as its predecessor. Browsing websites is done just as simple as with the desktop variant and there are almost no dissimilarities in loading times or page rendering.
