If you're having problems with Firefox, a refresh can help. Refreshing Firefox can fix many issues by restoring Firefox to its default state, while saving your essential information like bookmarks, and passwords.
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 Safe Mode to troubleshoot issues, before you refresh Firefox.
- Click this Refresh Firefox button directly, if you are viewing this page in Firefox. This won't work if you are using a different browser or a mobile device.
- You can also find a Refresh Firefox button at the top of the Firefox about:supportTroubleshooting Information page.
- To continue, click in the confirmation window that opens.
- Firefox will close to refresh itself. When finished, a window will list your imported information. Click and Firefox will open.
Note: There's a Refresh Firefox button in the Firefox Safe Mode window, if you can't start Firefox normally. You can also do a manual refresh by creating a new profile and transferring your important data to the new profile.
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.
