Multiple tabs in a web browser are great. If they persist a restart of your browser, you quickly use them as a read-later list. In such a case you don’t want to close the wrong tab. Unfortunately, this happens more often than you want. But there is a simple way to reopen the last closed Tab that works in most browsers.
