Firefox 3.1 can’t send Gmail emails

This is an update to the post below. I installed Firefox 3.1 beta2 and was surprised that the Send and Discard buttons in Gmail would not work when editing an email. In the Gmail v1.0 layout all would be fine. I searched for the issue but couldn’t find anyone else who had this problem. After a while I realised it might be one of my add-ons. And alas it seems to have been the GMail S/MIME encryption add-on. Somehow that must have skewed the JavaScript somewhat. Disable the add-in and all is well.
