I just followed the link (as I always do) to open a ticket and after dutifully filling in the blanks, click 'Submit' and the page reloads, but doesn't move on to actually open a case.
I was going to assume that it was just me, but saw in another threat that someone else had the same experience.
I know Firefox released an update this morning (or at least my browser niticed it and upgraded this morning) so that may well be it.
Any one else got the problem?
