This works in IE but not in mozilla.

Expected Results:  
Fired the event as it does by clicking on the selectobox by mouse.

It works for me using the testcase from bug 260850.
https://bugzilla.mozilla.org/attachment.cgi?id=159791&action=view

Works in Mozilla1.7 and in the latest 1.8a build of Firefox.

Maybe you could add an attachment which shows the bug?

If the select has a size="1" (or no defined size), then keyboard arrows do not
fire the onchange event. And then, I believe that would be bug 126379.
Mozilla 1.8a4 build 2004092505 under XP Pro SP2 here.
