AJAX is the one feature people can point to as something good that came from Internet Explorer. That and maybe their take on the box model. But virtually everything else they got wrong. Worse yet, they got complacent with their lead and web development stalled for years as a result. Other browsers have done far more to get us to where we are. Chrome introduced a modern security model and many useful APIs and protocols (including HTTP/2). Firefox popularized the concept of browser extensions and developer tools like Firebug. Safari made much possible by opening WebKit, such as Chrome and mobile browsers. Opera invented half of the original browser concepts including tabbed browsing. AJAX was largely responsible for the initial push to modern, dynamic websites, but it doesn't score enough points to make Microsoft the good guy in this history.
