title: JQuery toggle/slider flicker in Firefox
body: <p>Hmmm... I have read about this issue on various other threads here on stackoverflow but am still experiencing the problem on my work in progress (without quite as much exciting jQuery involved)</p>
  
  <p><a href="http://www.thebeverley.com" rel="nofollow noreferrer">www.thebeverley.com</a> </p>
  
  <p>Simple toggle that expands fine but flickers on collapse - you will need to scroll down to use the same button to collapse.  Seems only in FF 3.5.7 (mac) - works as expected in Safari.  Have tried various overflow:hidden permutations on #main id and elswhere, and removed href # completely now in case of some conflict.  Still no joy.</p>
  
  <p>Am I missing something or can someone point me in the right direction perhaps?</p>
  
  <p>Many thanks,
  D</p>
