I used different methods like this one but it seems none of them are working. These are steps I'm doing:

  • Closing firefox
  • Deleteing new logins.json and key4.db
  • copying old logins.json and key3.db

Well ff-password-exporter only works for key4.db, However I think my only hope is installing those old versions of firefox and export those passwords in csv format and somehow import them in new firefox.
