Configured drop-down background image selection does not work in Firefox 30

Configured selection of a drop-down background image does not work in the latest version of Firefox 30, but it works fine in other browsers (Chrome, Opera, IE11, Safari).

The below styles worked fine from Firefox 21 to 29, but it didn't work in Firefox 30.

select {
  background: url(dropdown_arw.png) no-repeat right center;
  appearance: none;
  -moz-appearance: none;
  -webkit-appearance: none;
  width: 90px;
  text-indent: 0.01px;
  text-overflow: "";
}
