I can reproduce this too actually. It's been reported a few times to our bug tracker too, and seems to require Firebug to be installed to trigger it. It happens only when opening the "Firebug UI Location" submenu.
The crash occurs when calling nsINode::OwnerDoc() on the menupopup associated with this menu, because mNodeInfo is null. Why would this happen?? :/
(Note, I'm the developer of the addon which seems to cause this crash)
