Hi, when I use Firefox, whenever I go to a new page I get a pop-up message saying 'Alert: The document contains no data.' I then have to click 'OK' numerous times to get the pop-up to go away, which is past annoying. Anyone any ideas of how to stop this pop-up? Obviously I could use Internet Explorer or another browser but I find Firefox more convenient and would prefer to continue using it. Thanks in advance :)
