你称之为游标是什么？ （它们是列表滚动条中的箭头吗？）
在我的Mac上，箭头键和/或键盘向下：
- IE滚动窗口
- FF做你说你的IE做的

我想您未提出的问题是如何获得一致的行为？ -
答案是不要使用select来触发onchange事件（这可能不是你想要听到的
）。
W3C规范说，当控件失去焦点时，onchange应该触发
（如果值已经改变）。 IE不会等待，只要选择了选项，它就会激活
。如果您使用键盘，Firefox会等待，但是如果您使用鼠标则不会等待
。
各种浏览器和规范之间还存在其他不一致之处，
遗憾的是结果有点混乱。
如果你解释一下你想要做什么其他一些解决方案可以是
建议。

完全没有：
我的Mac上的
我的FF（doctype transitional 4.0）
它会在每次更改时触发（按键盘的箭头键或点击）
（通过升降机或鼠标滚动列表 - >没有变化或火灾）
各种浏览器之间存在其他不一致之处规格，不幸的是结果有点乱。
不幸（汤希尔）

I have a <select> object that i''ve set up an onchange event that fires
in IE fine when I use the cursor up and down in the list, but If I use
the cursor up and down in Firefox the event doesn''t seem to fire until
I''ve left the field....If i use the mouse all is fine, only when using
the cursor keys does it not fire the onchange event in FF.
Thanks for any help in advance.

What do you call cursors ? (are they arrows in scrollbar of list ?)
on my Mac, with arrow keys up and/or down of keyboard :
- IE scrolls window
- FF does what you say your IE does

I guess your unasked question is "How do I get consistent behaviour" -
the answer is to not use a select to fire onchange events (which is
probably not what you want to hear).
The W3C spec says that onchange should fire when the control loses focus
(provided the value has changed). IE doesn''t wait, it fires as soon as
the option is selected. Firefox does wait if you use the keyboard, but
not if you use the mouse.
There are other inconsistencies between various browsers and the spec,
unfortunately the result is a bit of a mess.
If you explain what you are trying to do some other solution can be
proposed.

Not at all :
on my Mac with my FF (doctype transitional 4.0)
it fires on each change (by keyboard''s arrow key or by click)
(scrolling list by lift or mouse well -> no change or fire)
There are other inconsistencies between various browsers and the spec,
unfortunately the result is a bit of a mess.
unfortunatly (soupir)
