title: i can't see more my global object created by Components.utils.import("resource://gre/modules/myfile.jsm") in firefox 17
body: <p>I have used next code to create MyGlobalObject in my MultiWindows application in firefox 15- .</p>
  
  <pre><code>netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
  Components.utils.import("resource://gre/modules/MyGlobalObject.jsm");
  </code></pre>
  
  <p>My file MyGlobalObject.jsm is very simple:</p>
  
  <pre><code>var EXPORTED_SYMBOLS = [ "MyGlobalObject" ];
  if ("undefined" == typeof(MyGlobalObject)) {
      var MyGlobalObject = {};
      MyGlobalObject[0]=1;
  }
  </code></pre>
  
  <p>Since firefox 17+ this code doesn't operate.
  I have created add-on with next main.js:</p>
  
  <pre><code>exports.main = function() {
     var { Cu } = require("chrome");
     Cu.import("resource://gre/modules/MyGlobalObject.jsm");
  };
  </code></pre>
  
  <p>Nevertheless I can't access MyGlobalObject in my Javascript-code inside of my application.
  In what my misunderstanding programming for firefox 17+ consists?</p>
