title: Fullscreen video doesn't allow scrolling on firefox
body: <p>I'm using the fullscreen.js script and in one of my screens I will have a fullscreen Vimeo video. Apparently this will cause issues in FF and prevents me from scrolling up or down as soon as I reach the screen with the video. The issue was submitted to the GitHub page of the script but the author dismissed it as it's a FF issue (<a href="https://github.com/alvarotrigo/fullPage.js/issues/803" rel="nofollow">https://github.com/alvarotrigo/fullPage.js/issues/803</a>).</p>
  
  <p>I'm using all this with foundation CSS for the responsive video:</p>
  
  <pre><code>&lt;div class="flex-video widescreen vimeo"&gt; 
      &lt;iframe src="&lt;?php the_sub_field('video') ?&gt;" 
          width="400" 
          height="225" 
          frameborder="0" 
          webkitAllowFullScreen 
          mozallowfullscreen 
          allowFullScreen&gt;&lt;/iframe&gt; 
  &lt;/div&gt;
  </code></pre>
  
  <p>The bug is this one: <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=779286" rel="nofollow">https://bugzilla.mozilla.org/show_bug.cgi?id=779286</a> but I don't see that it was solved on FF 36 on Mac. The issue is not happening on chrome either.</p>
  
  <p>Here is an example of the issue by someone else on the GitHub thread: <a href="http://jsbin.com/tunove/1/edit?html,output" rel="nofollow">http://jsbin.com/tunove/1/edit?html,output</a></p>
