The difference between Firefox and IE is as follows:
Ie6.0, ff1.06 +:
Clientwidth = width + padding
Clientheight = height + padding
Offsetwidth = width + padding + border
Offsetheight = height + padding + border
Ie5.0/5.5:
Clientwidth = width-border
Clientheight = height-border
Offsetwidth = width
Offsetheight = height
(The margin attribute in CSS is independent of clientwidth, offsetwidth, clientheight, and offsetheight)
