Hello,

Firefox automatically creates backups of your bookmarks, which can be helpful if your bookmarks are lost or missing. To recover them, follow the instructions below.

1. Use one of these methods to open the Bookmarks Library window:
   • Firefox 29 and above: Click the Bookmarks button and select Show All Bookmarks.
   • Previous Firefox versions: Click the Firefox button and click on Bookmarks. (If you don't have a Firefox button, click the Bookmarks button or Bookmarks menu item and select Show All Bookmarks.)
2. At the top of the Library window, click on Import and Backup and select Restore.
3. Click the date of the bookmark backup you want to recover.
4. In the new window that appears, click OK.
5. Your bookmarks from the selected date should now be restored.

For more information, see the Restore bookmarks from backup or move them to another computer article. For other solutions, see the Recover lost or missing Bookmarks article.

Did this fix your problems? Please report back to us!

Thank you.

Thanks for responding. When I went to "Restore" there were only two dates there (the two days since I upgraded to Windows 10.)

Do you have an "C:\Windows.old" folder?

If you have a "C:\Windows.old" folder with personal data from a previously installed Windows version then you can recover personal data from a previously used profile in this backup.

• C:\Windows.old\Users\<user name>\AppData\Roaming\Mozilla\Firefox\Profiles

You can copy files like these to the current Firefox profile folder to recover specific data.

• bookmarks and history: places.sqlite
• bookmark backups: JSON backups in the bookmarkbackups folder
• SQLite files like cookies.sqlite (cookies) and formhistory.sqlite (saved form data)
• logins.json and key3.db (decryption key) for Passwords saved in the Password Manager
• cert8.db and possibly cert_override.txt for (intermediate) certificates stored in the Certificate Manager
• persdict.dat for words you added to the spelling checker dictionary
• permissions.sqlite for Permissions and possibly content-prefs.sqlite for other Site Preferences
• sessionstore.js for open tabs and pinned tabs and tab groups

You can use this button to go to the current Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
