I apologize – the latest script updated which reduced dependencies on keystrokes seems to have introduced issues. (I have been testing 1.2 which is not publicly released yet and had assumed it was related to that). In my own use of FireFox (for a few projects/tasks; I use Safari for the rest), the issue that you report only seems to occur about one time out of 20 or so.
Are you seeing the issue every time you “Copy as Link” in FireFox?
It’s a holiday in Canada today (labour day) so we might not be able to update the integration server today; but I will post the prior set of integration scripts here.
