вызываем на странице
if (is.gecko) // переменная определяющая NN
{
emulateEventHandlers(["contextmenu"]); например эмулировать событие на контекстное меню
emulateAttachEvent();
extendEventObject();
extendElementModel();
emulateHTMLModel();
emulateAllModel();
}
собственно определиь элемент у кого событие
window.event.srcElement // для всех
приаттачить событие
object.attachEvent("onclcik", function_name) // для всех
и т.д.

А>< div onmousemove="javascript:test('object'">
Можно просто передать объект:
<div onmousemove="test(this);">
