Answer : firefox extensions development- getting undefined

OK, got it. Find the code below.

                       
         
           
           
             function GetCMSMSpassive() {
  ret_status=false;
  var jQ = jQuery.noConflict();
	jQ.ajaxSetup({async: false});
  var verionDoc='http://'+window.top.getBrowser().selectedBrowser.contentWindow.location.host+'/doc/CHANGELOG.txt';
  jQ.get(verionDoc, function(data) {
	  var re = new RegExp(/(?:Version)\s+(.*?)\-(.*?)/);
	  var m = re.exec(data);
	  if (m == null) {
	      ret_status=false;
	  } else {
             ret_status =m[1];
	  }
	});

return status;
}
