$(function() {
// HIDING THE CLASS
$(".ad-nav").css("opacity","0.0");

// ON MOUSE OVER
$(".ad-nav").hover(function () {

// SET OPACITY TO 100%
$(this).stop().animate({
opacity: 1.0
}, "slow");
},

// ON MOUSE OUT
function () {

// SET OPACITY BACK TO HIDE
$(this).stop().animate({
opacity: 0.0
}, "slow");
});
});

I am hiding a Div and showing it on mouse over. Fade Animation is smooth on Safari but a bit choppy FF. Can anyone come up with a solution to make it run smoothly on both? thanks.
