tags not functioning

Having an issue when creating question (so far only happening with questions posting to SDL Trados Studio community--I can add a tag here)  in the forum--When I try to put in a Tag it will not let me put anything in that section. It actually sends me to a new blank screen.  Some times I can backup and get to the message I create, but other times have had to start over.

What would be causing this?

Oh, using latest version of Firefox.

Thanks in advance
