title: Fotorama navigation in Firefox
body: <p>I'm using the Fotorama image script on my website. I have data-allowfullscreen="native".  When I go into full screen in Firefox, the navigation and return from full-screen buttons sometimes disappear.  If I click on either the right or left of the image, I can go forward or back.  To exit full screen I have to press the Esc key.  The issue only appears to be with Firefox.  I put the code for my page below. </p>
  
  <pre><code>&lt;td width="1008"&gt;&lt;div class="fotorama" data-width="950" data-max-width="100%" data-max-height="97%" data-allowfullscreen="native"&gt; 
  &lt;img src="../../images/1979/02/1979-02-1.jpg"&gt;
