Vasu, Iam a kind of new bee and I need to do the same thing as what you have done. Need my C++ XPCOM to call JS function (page script or content script). Since it is not supported now, it has to be glued vie JS XPCOM. Do you have the working example as how you done? I need the working example badly.
