I need to be able to detect IE 9, IE 10, IE 11 and the latest from Firefox and Chrome. The old method using the user-agent string is unreliable and not recommended. There is a different approach called, "Feature Detection". But I need to know what features to test to determine the browser. I can write it myself, or if there is a handy dandy API using feature detection already written that would be OK too.
