My friend Kieran Barker wrote a great article on using
target="_blank" on links, and why it’s bad and you shouldn’t do it.
Chris Coyier did a great job documenting why you generally shouldn’t use
target="_blank" a couple of years ago, but Kieran writes about a security issue I didn’t know about.
If a user clicks on one of your links which has
target="_blank"set, the new page will have access to your page’s
windowobject via the
window.openerproperty. Does that sound like a bad thing? Because it is. The other page could redirect yours to a malicious URL.
