Computer crashed and OS was unrecoverable and now you want to recover your bookmarks to your new OS? Reinstall Mozilla Firefox, under Bookmarks, go to organize bookmarks, and click Import and Backup at the top. This was done on Moz FF 3.6.
Using your old hard drive as an external/internal drive, navigate to DRIVE:\Documents and Settings\USERNAME\Application Data\Mozilla\Firefox\Profiles\SOMESTRING.default\bookmarkbackups and select the latest JSON file to import.
That’s it!
