There is one IE9 feature that I miss in Chrome or Firefox: "Preserve Favorites website data" under Delete Browsing History. With that I can delete all cookies after a session but my logins stay active. And I don't need an extension for it. Every browser should support that. And the OS integration of IE9 on windows 7 is superior to the competition.
