title: Script to block popups
body: <p>AdBlock sometimes fails to block popups, so using Greasemonkey I want to write my own popup blocker using jQuery.</p>
  
  <p>Is there a way I can intercept the clicks and detect if it's going to open a popup?</p>
  
  <pre><code>$('.popupLauncher').each(function(){
      if( /* $(this) will open a popup */ ){
          return false;
      }
  });
  </code></pre>
  
  <p>With what can I replace <code>/* $(this) will open a popup */</code> ?</p>
