Craig, does it happen in safe-mode or a new profile?  See bug 1294933 for add-ons suspected of causing this.

When I restarted in safe-mode, the dock menu was missing everything.  So I just restarted FF normally and since I also have the Saved Password Editor extension that was mentioned in the other bug report, I disabled that.  The dock icon menu worked normally for several hours.  Then I re-enabled the Saved Password Ediror extension.  It has only been a couple hours, but so far the dock icon menu is working properly.  If it keeps working, it seems that disabling and then re-enabling a plugin solved the problem (as was the experience mentioned in the other bug report).
