title: Close firefox tab from javascript
body: <p>I want to close Firefox tab from JavaScript. Please do not misunderstand me. I am not trying to close popup window but tab. I know JavaScript cannot close the window which it has not opened. Therefore I tried below code but it works in all browsers but not in Firefox.</p>
  
  <pre><code>window.open('','_self','');
  Window.close();
  </code></pre>
