Firefox stores all your settings and personal information in a profile folder. The refresh feature creates a new profile folder and saves your important data.

The refresh feature removes add-ons normally stored inside the Firefox profile folder (such as extensions and themes). Add-ons stored in other locations are not removed (although any modified preferences are reset).

Firefox will save these items:

  • Bookmarks
  • Browsing and download history
  • Passwords
  • Cookies
  • Web form auto-fill information
  • Personal dictionary

These items and settings will be removed:

  • Website permissions
  • Modified preferences
  • DOM storage
  • Security certificate and device settings
  • User styles (chrome subfolder containing userChrome and/or userContentCSS files, if previously created.)
Note: The refresh will place your old Firefox profile on your desktop in a folder named “Old Firefox Data”. If your problem persists, you can partially restore lost information by copying files to the newly created profile. If you no longer need this folder, delete it because it contains sensitive information.
