For years the most popular browser, Microsoft's Internet Explorer's rate of use has increasingly decreased through the years. However, its newest version, Internet Explorer 9, features some interesting things, and make it worthy of consideration again: It is faster, has a cleaner interface, smaller notifications, security is upgraded, and features tab isolation (so that not all your tabs crash when one does), a feature first seen in Google's Chrome. It also features one box for both addresses and web search, again something Chrome started doing, and a download manager. It supports HTML5, CSS3 and SVG. The downside is that it only works for Windows Vista and Windows 7.
