title: Really Strange OpenCart (Product Specials) + FireFox (Cache?) Issue
body: <p>The following page usually shows a special "sale" price <a href="http://tinyurl.com/9ja5eu2" rel="nofollow noreferrer">http://tinyurl.com/9ja5eu2</a> (I think it's deactivated right now).  As shown in the image, it fails to show the price on "some" computers and in "some" browsers (Firefox).  </p>
  
  <p>I logged in remotely to one of the erroneous computers and launched it up in Firefox and I watched it work correctly in IE but not work in Firefox.  I cleared the cache in Firefox and reloaded the page, but it still didn't show the sale price.  </p>

  <p>Does anyone have any idea why the "special" price wouldn't show up in some computers in Firefox?  It works fine on my home and work computer in Firefox and all other browsers, just not on other people's computers.</p>
  
  <p>Thanks for your help.</p>
