title: No resize dropdown list/select box arrow
body: <p>On my website I've got a contact form with a dropdown list/select box. The box has a font-size of 14px. But only in Firefox the arrow of the dropdown list/select box (on the right) is resized according to the font-size. Is it possible to dissable this?</p>
  
  <p>So the heigher you set the font-size, the larger the arrow in Firefox will be.</p>
  
  <p>It has to be some kind of CSS style, because I've used 2 different scripts, and it's only occuring by 1 script.</p>
  
  <p>Thanks in advance! :)</p>
