Thanks for the reply. I tried to use the same code base for Moz 1.9 which
worked fine in Moz 1.8. The code that I am trying on simple google home page
only.

Here is the sample code written in C++.

	nsCOMPtr<nsIWindowMediator> iWindowMediator =
do_GetService(NS_WINDOWMEDIATOR_CONTRACTID, &result);

	result = iWindowMediator->GetXULWindowEnumerator(0, getter_AddRefs(enum));
// enum - nsISimpleEnumerator
	//iWindowMediator->Release() ; // This is commented in Moz 1.9 as I am
getting compiler error.
	

	nsCOMPtr<nsISupports> pis ;
	nsresult result ;
	while(((result = enum->GetNext(	getter_AddRefs(pis))) == NS_OK) && next ==
0 && pis != 0 )
	{
		nsCOMPtr<nsIXULWindow> webShellWindow(do_QueryInterface(pis, &result));
		if (webShellWindow != 0 )
		{
			webShellWindow->GetDocShell(getter_AddRefs(DocShell)); // DocShell -
nsIDocShell
			nsIDOMWindowPtr domWindow(do_GetInterface(DocShell));

			nsIDOMDocumentPtr domDocument = 0 ;

			if (window->GetDocument(getter_AddRefs(domDocument)) == NS_OK)
			{
				nsIDOMNSDocumentPtr doc = do_QueryInterface(domDocument) ; // This is
working fine
				nsIDOMHTMLDocumentPtr htmlDocument = do_QueryInterface(domDocument) ; //
This is not working and getting null reference
			}

		}
	}


Please let me know if I did any thing wrong.
