I was doing some travel research, Firefox crashed and wouldn't restart. I then tried to refresh Firefox and it save my "Old Firefox Data" in a folder on my desktop. I tried to restart Firefox but it kept saying my Profile was missing. I then followed directions to create a new Profile so I could get Firefox to open up. This worked and now I want to get my old bookmarks into my new profile from the "Old Firefox Data" folder.

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

If you have an "Old Firefox Data" folder on the desktop then you can recover some personal data from a recent profile in that folder. You can copy/transfer files like these to your current Firefox profile folder.

  • bookmarks/history: backups in the bookmarkbackups folder and possibly places.sqlite if you really need the history
  • other 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
  • permissions.sqlite and possibly content-prefs.sqlite for Permissions and Site Preferences
  • cert8.db for stored intermediate certificates (Certificate Manager)
  • sessionstore.js for open tabs and pinned tabs and tab groups

You can recover more personal data.

These can't get your data back, but will help in the future.

These add-ons can be a great help by backing up and restoring Firefox

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backup of files that you choose.
