The advantage of selfdestructingcookies is that, without any intervention, it allows cookies while the site that set them is open in a tab, but once the tab is closed the cookies are promptly deleted (configurable delay).

Same with Vanilla cookie manager on Chrome, except I don't think it deletes localstorage, flash cookies, etc because of limitations of Chrome's api for extensions. I think the attitude with Chrome is that you're supposed to use Incognito windows for this purpose.
