title: Firefox jquery flicker bug problem
body: <p>This is possibly a really silly question but I've stared at this code way too long for it to make sense!</p>
  
  <p>I'm having problems with a flicker of the screen in firefox; It is related a filtering script...</p>
  
  <p>I have a website that is a one page vertical scroll; with different anchors to define sections and a smooth scroll script to make it pretty...</p>
  
  <p>See the example here: <a href="http://www.moonshine.net.au/index-new.html" rel="nofollow noreferrer">http://www.moonshine.net.au/index-new.html</a></p>
  
  <p>I've tried everything... Please help me, I'm begging you, my eyes hurt!</p>
