First, Mozilla doesn't implement document.frames, it implements
window.frames - as does MSHTML IHTMLWindow2. So to implement
IHTMLDocument2.get_frames, you will likely need to use nsIDOMWindow,
not nsIDOMHTMLDocument.
I see nsIDOMWindow is accessible from here:
http://mxr.mozilla.org/seamonkey/source/embedding/browser/activex/src/control/MozillaBrowser.cpp#1745
CIEHTMLDocument holds a pointer the the CMozillaBrowser (mControl)
which you can use to then get the frames.
