Hi frank
I think you should use the forum at http://forums.mozillazine.org/viewtopic.php?f=48&t=540112&st=0&sk=t&sd=a if you have problems but check any dials that you have created using "launch:", you might have left one pointing at nothing. :woops

This review is for a previous version of the add-on (0.7.2.11).
