I cannot locate the encrypted password file to move to my new PC. Please advise on its location.

Chosen solution

You need the two files signons.sqlite and key3.db to transfer or backup the passwords.
The key3.db file stores the encryption key and the correct version of this file is required to be able to decrypt the passwords.

What are the fully-qualified locations of the two files you mention?

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

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Main profile folder:

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

Cache folder location as shown on the about:plugins page:

  • C:\Users\<user>\AppData\LocalMozilla\Firefox\Profiles\<profile>\

The "Application Data" folder in XP/Win2K and the "AppData" folder in Windows Vista and Windows 7 and later versions are hidden folders.
