Problem is that youtube link reloads page on chrome and not on firefox?

Thanks.

var link = "http://www.youtube.com/watch?v=QU5DhngJfr8"

var object = '<object height="385" width="640">'

            + '<param value="'+link+'" name="movie">'

            + '<param value="true" name="allowFullScreen">'

            + '<param value="always" name="allowscriptaccess">'

            + '<embed height="385" width="640" allowfullscreen="f" allowscriptaccess="always" type="application/x-shockwave-flash" src="'+link+'">'

            + '</object>'; 

jQuery('<div>') 

      .html(object) 

      .dialog({   closeOnEscape: false, 

                  autoOpen: true, 

                  resizable:false, 

                  title: 'test',

                  modal: true, 

                  height:440, 

                  width:675, 

                  close:function(event){ 

                        jQuery(this).remove(); 

                  } 

      });
