non so perchè, ma non ti legge il focus sull'iframe. Probabilmente su FF sente diversamente l'iframe.
te l'ho risolto, per modo di dire, cosi:
Codice PHP:
$(document).ready(function(){
// Using multiple unit types within one animation.
$("iframe").hover(function(){
$("body").animate({
opacity:".2"},500);
$("#test").animate({
marginLeft: "-30px",
opacity:"1"}, 500 );
$("#frameI").animate({
width: "630px",
marginLeft: "-20px",
marginRight:"-24px",
opacity:"1"}, 500 )},
function(){
$("#test").animate({
width: "300px",
marginLeft: "110px"
}, 500 );
$("#frameI").animate({
width: "312px",
marginLeft: "-35px",
marginTop:"-50px",
marginBottom:"-4px"
}, 500 );
$("body").animate({
opacity:"1"},500);
});
});
