John Resig provides an alternative. I haven't tried it in the browsers you mention. Try it and let us know.

http://ejohn.org/blog/ecmascript-5-objects-and-properties/

Object.freeze = function( obj ) {
  var props = Object.getOwnPropertyNames( obj );

  for ( var i = 0; i < props.length; i++ ) {
    var desc = Object.getOwnPropertyDescriptor( obj, props[i] );

    if ( "value" in desc ) {
      desc.writable = false;
    }

     desc.configurable = false;
     Object.defineProperty( obj, props[i], desc );
  }

  return Object.preventExtensions( obj );
};
