I've never saved, nor let anything auto-save, a log-in nor password, master nor otherwise.  Mozilla pages do not contradict that. I don't have, nor wish to, Lockwise, etc.

      I've enabled permanent cookies storage, and pop-ups appearing, for that Options page. Strict blocking changed to Standard for that page: no help.  

    Thank you for whatever help you can give!
