Internet Explorer 11:
IE11 is now available for Windows 7 and 8, unfortunately not for Vista or XP. This latest version is faster, trimmer and far more compliant with HTML5. This is a huge improvement for Microsoft. IE includes tab-pinning and leading hardware acceleration and supports WebGL and SPDY but not WebRTC. A great privacy tool includes Do Not Track enabled by default and Tracking Protection feature.
