title: Firefox 11 and GeoLocation denial callback
body: <p>Things worked okay is Firefox 10.x but with the upgrade to Firefox 11 has thrown up a problem.</p>
  
  <p>I use </p>
  
  <pre><code>navigator.geolocation.getCurrentPosition(success, failure)
  </code></pre>
  
  <p>but in FF11 the failure callback is not executed when the user denies sharing location by selecting "Not Now".</p>
  
  <p>Any suggestions?</p>
