No Problem 

Now visit this link 

http://thewhitehatblog.blogspot.com/2017/09/whitehat-testing.html

Actual results:

Redirected to Data Uri


Expected results:

Shouldn't Redirected to Data Uri
Many sites including Facebook and Google is affected by TabNapping.So attacker can redirect Firefox users to data Uri very easily through Facebook and other sites but can not redirect in chrome.
If tabnapping is a site problem, how is a data: url any different/worse than any other arbitrary attempt to spoof the user through tabnapping? Either the user looks at the address bar or they don't, and if they do a data: url isn't facebook.com any more than spoofer.com is.

To the extent this bug is "behave like Chrome wrt data: urls" that's bug 1401895
