i have the same problem. mouseout over input-element not working in ff3 ...
my code: $(" #nav_list li").hover(function(){ $(this).addClass('hover'); $(this).find('ul:first').css({visibility: "visible",display: "none"}).show(0); },function(){ $(this).removeClass('hover'); $(this).find('ul:first').css({visibility: "hidden"}); }); also guess, that this has something to do with the mouseout event in ff3 ...
