Hi, I had to reset my MS Surface Pro and have lost all my bookmarks. I used the option to reset and keep personal settings. Can I get my Bookmarks back? Rgds Gary

You can check if you have the C:\Windows.old folder with your previous personal data.

Location used for the main profile that keeps your personal data (Root Directory on about:profiles).

  • C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>

Note that in Windows "AppData" (Mac: ~/Library; Linux: ~/.mozilla) is a hidden folder.


You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data. Note that best is to avoid copying a full profile folder.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
