title: Getting weird 404 error in my online portfolio. Firefox only issue
body: <p>When I click on one of the icons for my online art portfolio, it is supposed to make the picture pop up on the same page. However for Firefox, when I click on an icon, it goes to a 404 page. If I go back, that picture will pop up. I have been told that on the newest version of Firefox, or version 28 I think, has no issues. I have 27.something.</p>
  
  <p>This does not happen on any other browser.</p>
  
  <p>Also I made the animation of the picture popping up with Adobe Edge, the CC version.</p>
  
  <p>Here is my site- <a href="http://spencerheisedesign.com/gallery.html" rel="nofollow">http://spencerheisedesign.com/gallery.html</a></p>
  
  <p>Thanks!</p>
