Have you checked your JavaScript/error console because 'window' might 
not be what you think it is, but you can use something like this:

   observe: function(aSubject, aTopic, aData)
   {
     switch (aTopic) {
       case "domwindowopened":
         var self = this;
         var window = aSubject;
         window.addEventListener("load",
           function() {
             self._onWindowOpened(window);
             window.removeEventListener("load", arguments.callee, false);
           },
           false);
         break;
   ...

   _onWindowOpened: function(aWindow)
   {
     if (aWindow.document.documentElement.getAttribute("windowtype") != 
"navigator:browser")
       return;
   ...

That gives you the 'right' (chrome) window object ;)
