title: Open new tab or window using confirm() form
body: <p>I try to open some URL in new tab or window, but any Webkit based browser or Opera are block them. I trying many variants to make that, like <code>window.open()</code> etc. like this:</p>
  
  <pre><code>if(c&lt;q){var l='url';
  var g=$('&lt;form action="'+l+'" style="display:none;" target="_blank"&gt;&lt;/form&gt;')
  .appendTo('.append').eq(0);
  if(confirm('some text')){g[0].submit();}}
  </code></pre>
  
  <p>but any results...
  - this code not blocked only on Firefox. How to create the right one?
  Thank's for any help!</p>
