Security - complete mess

[mikh43]

1. Tried to raise a new ticket about something else!
2. Firefox rejected the security certificate on the josm.openstreetmap.de site - so I overrode Firefox to make an exception for JOSM. No known changes in my own configuration.
3. JOSM wanted a user name and password but repeatedly rejected mine.
4. Tried to create a new account but it wouldn't do so - just kept on asking for a username and password.
5. Not entirely sure how I eventually hacked through to the newticket page but here I am - at last.
6. Something seems to have gone seriously wrong with authentication on the site.
