User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/530.5 (KHTML, like Gecko) Chrome/2.0.172.33 Safari/530.5

This is the example from mozilla development center. 
https://developer.mozilla.org/samples/dragdrop/dragevents.html
The resource code is in:
https://developer.mozilla.org/samples/dragdrop/dragevents.txt

The problem is we can not catch the "drop event" or 
the follow code "dragService.getCurrentSession().canDrop = true;" throw an exception. 

Reproducible: Always

Steps to Reproduce:
1.go the link "https://developer.mozilla.org/samples/dragdrop/dragevents.html:"
2.do drag and drop the image
3.Can't not drop 


Expected Results:  
This is the code: 
function eventReceived(event)
{
  if ((event.type == "dragenter") || (event.type == "dragover"))
    dragService.getCurrentSession().canDrop = true;
  var output = document.getElementById("output");
  output.textContent += event.type + "\n";
}

Except result: document should show "drop"

Whatever this example, it should just be removed as it uses the now deprecated api.

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.
