I've used Firefox daily for more than 15 years. Suddenly, it locked me out and covers my screen with a dropdown asking for a Master Password. There is no way to get past it as I have no record of ever having or using one. eMails to Mozilla about this have gone unanswered. I am happy to erase and replace, but then I lose all the Passwords I have stored Firefox . How do I get the words I need and get to the Passwords? Thank you.
