echo "<script language=\"javascript\" type=\"text/javascript\">
  function banner_types(banner_c_id) {
   if (banner_c_id == 0) {
      banner_id_0.style.display = 'block';
      banner_id_1.style.display = 'none';
      banner_id_2.style.display = 'none';
      banner_id_3.style.display = 'none';
    } else if (banner_c_id == 1) {
      banner_id_0.style.display = 'none';
      banner_id_1.style.display = 'block';
      banner_id_2.style.display = 'none';
      banner_id_3.style.display = 'none';
    } else if (banner_c_id == 2) {
      banner_id_0.style.display = 'none';
      banner_id_1.style.display = 'none';
      banner_id_2.style.display = 'block';
      banner_id_3.style.display = 'none';
    } else if (banner_c_id == 3) {
      banner_id_0.style.display = 'none';
      banner_id_1.style.display = 'none';
      banner_id_2.style.display = 'none';

What is the difference in the behavior of the two browsers? Does it just not do anything in FF? Does an error show up? Do you have javascript enabled in FF?

No errors show, just not display div blocks
