How do i import password file from firefox old to firefox 120.0.1 using a CSV file?

Hi, Firefox, by default, does not show the "Passwords from CSV file" option. The right answer is here: https://support.mozilla.org/kn/questions/1366995

To enable importing of the csv file, you need to make the following preference in about:config true in your present profile : signon.management.page.fileImport.enabled That will add the option to import to Passwords.
