title: Using jQuery in Tampermonkey
body: <p>I'm using Chrome 27.0.1453.116 m and have enabled "Experimental Javascript", however I'm unable to get jQuery to run on Tampermonkey. </p>
  
  <p>I have tried:</p>
  
  <pre><code>// ==UserScript==
  // @name       My Fancy New Userscript
  // @require    http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js
  // ==/UserScript==
  
  var $ = unsafeWindow.jQuery;
  var jQuery = unsafeWindow.jQuery;
  </code></pre>
  
  <p>However, I get an error on the line <code>var $ = unsafeWindow.jQuery;</code> highlighting <code>unsafeWindow</code> saying unsafeWindow was used before it was defined. How to fix this?</p>
