Bootstrap 3 Styled Select dropdown looks ugly in Firefox on OS X

Answer 1

This is easy. You just need to put inside .form-control this:

.form-control{
        -webkit-appearance:none;
        -moz-appearance: none;
        -ms-appearance: none;
        -o-appearance: none;
        appearance: none;
}

This will remove browser's appearance and allow your CSS.
