I've been using Sync for a long time, my account password was saved within the browser, it just worked. After update to version 81, following things happened: - all of the settings set in the options as well as about:config were re-set to defaults, - I could not log into Firefox account with a password working perfectly until now, - when tried 'Forgot password procedure' I've received "email address returned" error. Is there anything I can do other than creating new account? Thanks
