It may be that the method you want is not defined in an IDL file at all, but
with custom code supporting only JS.  For example, to implement an
openDialog() method, I ended up with code:

        svc = components.classes['@mozilla.org/embedcomp/window-watcher;1']
                .getService(components.interfaces.nsIWindowWatcher)
        # Wrap in an nsIArray with special support for Python being able to
        # access the raw objects if the call-site is smart enough
        args = _nsdom.MakeArray(args)
        ret = svc.openWindow(self._comobj_, url, name, features, args)
        # and re-wrap in one of our "dom" objects
        ...

Although this relies on features only in the nsdom code, the underlying
point is that you may be able to convince the window-watcher to do what you
need, but sadly I've no time to dig deeper into this today...

Cheers,

Mark
