title: How do I close a firefox tab from a greasemonkey script?
body: <p>I have a greasemonkey user script with this single line of code...</p>
  
  <pre><code>window.close();
  </code></pre>
  
  <p>but firefox does not allow a user script to close a window (as reported by an error message in the error console)</p>
  
  <p>Is there a work around to this problem?</p>
