and it doesn't work except firefox

Answer 1

don't set fixed in CSS: it works in firefox, chromium, safari, iexplore

var div = $('#id');
div.resizable(
{
    stop: function(event, ui)
    {                       
        var top = getTop(ui.helper);
        ui.helper.css('position', 'fixed');
        ui.helper.css('top', top+"px");         
    }       
});
div.draggable(
{
    stop: function(event, ui)
    {           
        var top = getTop(ui.helper);
        ui.helper.css('position', 'fixed');
        ui.helper.css('top', top+"px");
    }
});

function getTop(ele)
{
    var eTop = ele.offset().top;
    var wTop = $(window).scrollTop();
    var top = eTop - wTop;

    return top; 
}
