Question: I am trying to detect ALL versions of IE by using jquery `$.browser.msie`. 
It works for 8, 7, 6, but it ignores IE9. Why is that and what is a solution for javascript to detect ie9?

JS version: jQuery JavaScript Library **v1.5**

Answer: 
As of version `1.9` of jQuery `$.browser` is no longer supported. Use `jQuery.suport` instead. With this change you'll need to check on what functionality you want to check. So just browser check is no longer supported in it. It is recommended to do a feature check instead of browser check.

[Docs here](http://api.jquery.com/jQuery.support/)
you can override the detection of IE noFullScreen: { msie: /msie [0-6]/, ... } to 
noFullScreen: { msie: /abcdefgh/ }
