X-Firefox is a free web browser based completely on Mozilla Firefox. The exception to the similarities lies in the fact that X-Firefox is portable.
As a portable application, X-Firefox can be run from virtually any location like a network drive or a USB flash drive. Installation is not required.
In terms of features, X-Firefox contains all of the features that can be found in the most recent versions of Mozilla Firefox. That includes tabs, bookmarks, private browsing, etc.
After you're done with X-Firefox, you can safely delete it along with all of your browsing history. Nothing should be saved in the Windows Registry.
Overall, X-Firefox is a portable version of Firefox; nothing more and nothing less.
