If you explictly check for objects which are part of the IE or Netscape 
4 model then Mozilla will happily ignore that code.
You might want to try
   function changeBgColor (element, new_color) {
     if (element && element.style) {
       element.style.backgroundColor = new_color;
     }
     else if (typeof element.bgColor != 'undefined') {
       element.bgColor = new_color;
     }
   }
that way if you pass in an element object the CSS inline background 
color will be changed with IE4+, Netscape 6+, Mozilla 1.0 and later, 
Firefox, Opera 7 and later and others.

Only IE 5.5 and later on Windows support window.createPopup, other 
browsers do not implement that function.

Because whoever wrote the code scripted for IE (and in the first 
function for Netscape 4).
