Please consider turning on send info to Mozilla before posting a question. This helps us help you.

They possibly are on the desktop in a folder called Old Firefox Data ok, this gives you the information to work with. https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings, follow the instructions here from the above URL : copying files to the new profile that was created.

Note : Firefox 57 Quantum release date Nov 14th https://www.mozilla.org/en-US/firefox/quantum/ Note : Legacy Extensions will be disabled and or removed.

Please let us know if this solved your issue or if need further assistance.

Your bookmarks should be migrated during a Refresh, so you did nothing wrong (unless you canceled the process in the middle...).

To supplement Pkshadow's advice, see also:

Does it work?

If you want to try a complete roll-back of the Refresh, there's no one-click feature for that, but with some copy/paste, it's possible. See, for example: I did a Reset of Firefox - How do i get add my 'Old firefox data' back?

You would normally first check if there is a possible "Old Firefox Data" folder on the desktop. If Firefox wasn't able to move the old profile to the desktop then you can check whether there possibly is an orphaned profile that may or may not appear in the Profile Manager.


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

You can go up one level to see if there are more profiles present.

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

Profiles created as the result of a refresh have a date stamp appended.


You can copy files like these with Firefox closed to the current profile folder to recover specific data. Note that you should be cautious with copying SQLite database files if you previously had problems.

  • bookmarks and history: places.sqlite
  • bookmark backups: compressed .jsonlz4 backups in the bookmarkbackups folder
  • cookies.sqlite for the cookies
  • formhistory.sqlite for 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.jsonlz4 for open tabs and pinned tabs

Hey all: these are all great ways to recover bookmarks and find them in the profile if they are not showing up.

What I want to know ggmyersjr, where are you looking? Because on a Firefox refresh, not all of the customization in the toolbar is restored. (product thinks users might be missing this, your personal experience can help out many other users with your reply!)

Please check each of these places if you have found that the profile folders above mentioned by these users has a recent timestamp.

Bookmarks > Show all bookmarks Click on the three bar menu then > Library > Bookmarks

If you were used to them being on the toolbar, you can add them back: Customize Firefox controls, buttons and toolbars

I very much look forward to your reply!
