Visualforce popup scrollbar issue for Mozilla

Did you ever try to open up popup window from visualforce using javascript? Something like

window.open('/apex/ContactDetail?id=' + conId,'','location=no,resizable=no,toolbar=no,status=no,menubar=no');

The above code works for all browsers other than new versions of Mozilla Firefox. You need to add extra tag in the method -

"scrollbars=yes"

So the method will be -

window.open('/apex/ContactDetail?id=' + conId,'','location=no,resizable=no,toolbar=no,status=no,menubar=no,scrollbars=yes');
