Website crashes are isolated to individual tabs, not entire browser windows. If a site crashes on one tab, the rest of your browsing session isn’t interrupted. You keep browsing, undisturbed. After the problem is identified, Internet Explorer 9 automatically recovers the tab. If one or more of your tabs closes or crashes unexpectedly, they’re automatically reloaded, and you’re returned to the site you were on before the crash. Internet Explorer 9 also includes new support for unresponsive websites, so that you will be prompted if the website you're trying to access is not responding or is timed out for some reason.
