How to Uninstall Firefox Completely (Remove Firefox Profiles, Data, etc).

This guide contains instructions on how to completely remove the Mozilla Firefox application and all Firefox's stored profiles (user data and settings) from a Windows system. Use this guide in order to fix Firefox problems or to totally remove the Firefox Web browser from your computer.

By default the Firefox Uninstall process via Programs & Features ("Add/Remove programs" in Windows XP) in Control Panel, doesn't remove the stored personal data (user data) and customizations from the system, so you have to remove all these remained data manually after uninstall. The personal data that stored from Firefox contains important information about you, like your bookmarks, passwords, history, etc., and by default are stored at this location on your computer:

• C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxx.default
