I've noticed that if I apply a transform on a select box focus (i.e. select:focus) in Firefox it first focuses the select box then you must click the select box again for it to actually drop down. Anyone else experience this? I tried looking for a bug at Mozilla but didn't see anything.
Webkit browsers (tested in chrome) act appropriately.
I'm on Firefox 3.6.7
Test case:
<!DOCTYPE html>
<html>
  <head>
    <style type="text/css">
    select:focus {
      -moz-transform: scale(1.05);
      -webkit-transform: scale(1.05);
    }
    </style>
  </head>
  <body>
    <select>
      <option>One</option>
      <option>Two</option>
    </select>
  </body>
</html>
I've opened a bug at mozilla https://bugzilla.mozilla.org/show_bug.cgi?id=581604
