If you can get hold of the nsIDocShell object (hopefully by getInterface 
on the callbacks but if not then getInterface on the window) then I 
think you can QI it to an nsIDocShellTreeItem, get its rootTreeItem, 
then getInterface on that to an nsIDOMWindow, then call 
getBrowser().getBrowserIndexForDocument(DOMWindow.top.document).
