I got the top bar saying "Do you want FF to remember your 'password' for this page (e.g. Facebook)"? and the 3 options: 'Remember', 'Never for this site' and 'Not now'. I pressed 'Remember' but nothing happens and the bar stays there. If I choose any other option, it disappears but the password is not saved. What can I do? This never happens before and it was working correctly. Thank you.
