Hi chrisjurk,

No I am sorry, if you have reinstalled the os and the profile folder is most likely no longer there, there is not way to recover the bookmarks unless you have a copy of that folder. But we can try this anyway if the bookmarks are lost with the instructions below.

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:
   • Click the Firefox button to open the menu and click on Bookmarks.
   • Click the Bookmarks menu and click on Show All Bookmarks.
2. At the top of the Library window, click the "Import and Backup" menu 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.

There are different ways to approach reinstalling Windows.

If you ran a disk/partition reformat before or during your reinstall, it would be very difficult to recover whole files (fragments yes, but those probably won't help very much).

If you reinstalled Windows WITHOUT doing a disk/partition reformat, look for a folder named:

C:\Windows.old\

If you find that, we could assist in drilling down to your old Firefox settings folder.
