I need to restore my firefox profile from a flash drive. I had to do a fresh win 7 install and need to restore my old profile so I can get to my old bookmarks.

Type about:support<enter> in the address bar.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

If you want to overwrite this profile, just copy from the thumb drive folder into this profile.

If you want to keep the present profile, create a new profile, then copy the thumb into it.

  • 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
