Not really how I usually write it...

+  function getModuleGlobal(module)
+  {
+    let result = Cu.getGlobalForObject(require(module));
+    if (result == window)
+    {
+      // Work-around for bug 736316 - getGlobalForObject gave us our own window
+      let {XPIProvider} = Cu.import("resource://gre/modules/XPIProvider.jsm", null);
+      let addonID = "{d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d}"
