Description Huzaifa S. Sidhpurwala 2017-04-19 06:26:35 UTC 
A mechanism to spoof the addressbar through the user interaction on the addressbar and the <code>onblur</code> event. The event could be used by script to affect text display to make the loaded site appear to be different from the one actually loaded within the addressbar.
