A version working with the Element Properties add-on (recent Fx versions) is available in the MozillaZine forums:

Maybe you could adapt this tiny change? :)

This review is for a previous version of the add-on (0.3.2).

As promissed in my earlier reply, the just released 0.4 cooperates with the Element Properties extension.
