NS part 2, works fine. OTOH, it may work from Mozilla again as well... as it worked most of the time for the last few months. So OK, it's a glitch, but can be solved in Mozilla really easy: click the reply with my mouse wheel, which opens it in a new tab, and then the proper content of the editbox appears.

Going back to Mozilla to test again.
