Hi, do you mean the Primary Password that protects your saved logins in your installation of Firefox? See: * [[Use a Primary Password to protect stored logins and passwords]] * [[Reset your Primary Password if you've forgotten it]] -- note that saved logins are lost If you didn't intend to add a primary password, do you have any backups you can use to recover your old saved logins? We can mention the files to transfer if you do. (Spoiler alert: logins.json + key4.db. [[Recover important data from an old profile]])
