This feature is available on Firefox for desktop or laptop computers.
If Firefox isn't working correctly, the Refresh Firefox feature can help. It restores Firefox to its default state while keeping your essential data like bookmarks and passwords. This can fix problems caused by add-ons, corrupted settings, or customizations.
Important: A Firefox refresh removes add-ons and other customizations, such as extensions, extension data, and preference configurations. If you've made accessibility customizations to Firefox, you may need to add them back after refreshing. Consider using Firefox Troubleshoot Mode to diagnose issues before you refresh Firefox.

What does the refresh feature do?
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 autofill information
- Personal dictionary
These items and settings will be removed
- Extensions and themes
- Website permissions
- Modified preferences
- Added search engines
- DOM storage
- Security certificate and device settings
- Download actions
- Toolbar customizations
- User styles (chrome subfolder containing userChrome and/or userContent CSS 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, we encourage you to delete it, since it contains sensitive information.
