title: after pressing browser's back button on firefox loading image keeeps on rotating
body: <p>I have div tag like this </p>
  
  <pre><code>&lt;div id="page-loader"&gt;
  &lt;img src="loader.png" alt="loading"&gt;&lt;/img&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>and script will run for every click on "a" tag</p>
  
  <pre><code>$("#page-loader").show();
  </code></pre>
  
  <p>whenever there is a click on <code>&lt;a&gt;</code> tag browser shows "loader.png" pic and moves to new page(depends on href). after I clicked firefox's back button, it goes to last page and shows "loader.png" pic and it keeps showing "loader.png" pic not at all stopped. Could someone please help me on this..?</p>
  
  <p>Thanks:)</p>
