I'm not an IT pro and the solution of moving passwords from one computer to another is clear as mud, telling me to type about: config in URL. I don't what that means nor how to do it. I've opened a new tab in firefox and typed "about: config" and got "invalid URL" please help

Note that it is about:config with only a colon between the two words.

You can export the logins in the Password Manager to a CSV file.

You need to enable import CSV in the Password Manager (about:logins) via the about:config page as this menu item is currently hidden for performance reasons.

  • about:config => signon.management.page.fileImport.enabled = true

You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data. Note that best is to avoid copying a full profile folder.

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