问题说明：
FF 没有 setCapture()、releaseCapture()方法

解决方法：
IE:

obj.setCapture();
obj.releaseCapture();

FF:

window.captureEvents(Event.MOUSEMOVE | Event.MOUSEUP);
window.releaseEvents(Event.MOUSEMOVE | Event.MOUSEUP);
if (!window.captureEvents) {
  o.setCapture();
} else {
  window.captureEvents(Event.MOUSEMOVE | Event.MOUSEUP);
}
if (!window.captureEvents) {
  o.releaseCapture();
} else {
  window.releaseEvents(Event.MOUSEMOVE | Event.MOUSEUP);
}
