Hi, Our site was using jQuery animation on links. We noticed that FF sometimes needed additional clicks to navigate, whereas IE did not. We unfortunately had to remove the jQuery animation because of this.
We were doing this:
$("#rss.CssMO").removeClass("CssMO").mouseenter(function(e){
var $this=$(this);
$this.children("img").stop(true,true).fadeOut();
}).mouseleave(function(e){
var $this=$(this);
$this.children("img").stop(true,true).fadeIn();
}).click(function(e){
var $this=$(this);
$this.children("img").stop(true,true);
});
Basically we were using fadein/out to smoothly reveal/hide a background image on the anchor tag.
