Reporter, this does look more like an extension problem. Please start Firefox in Safe Mode and check if that happens without any active extension. I suspect that the error will be visible because I cannot find such an identifier in the code base of Firefox.
Component: Menus → Toolbars
QA Contact: menus → toolbars
Version: unspecified → 3.0 Branch
Restarting with all plugins disabled solved the problem. Resetting the menus works as well. I will attempt to reactivate each plugin 1 by 1 to try to determine the plugin that has the problem.

Thanks Steven. You can get in contact with the add-on developers to get this thing fixed. For Firefox we only set fixed when a patch was checked into our code base. Thanks for your help.

It was caused by the Zend Studio Toolbar Firefox plugin. I have reproduced the error with just this plugin running and have since removed it from my system. I have also reported this as an error to Zend.
That's great. Thanks again.
