Styling select box with multiple options

[Hagendaz]

Hi,
I have two select boxes with multiple options next to eachother. Each box have 10 options/lines visible. I would like to have them look similar in IE and FF. However, in FF the selected options turn gray when the select box looses focus. Is there any way to have the options selected stay blue also after the box looses focus in FF?
Does anyone know? Thanks!

select {background:#39f;}
option {background:#fff;}
