Google is testing a new option so you can keep your super-recent browsing history secret
Your browsing history can be very revealing; there are countless reasons for not wanting a list of the sites you have visited to be seen by others. While it can be hard to maintain complete privacy, there are steps you can take on a local basis -- such as simply deleting your browsing history.
It is easy to see the deletion of browsing history as using a sledgehammer to crack a nut, and for a very long time it was very much an "all or nothing" approach. Over time, Google and others introduced options to limit how much browsing history should be deleted, and now Chrome users are being offered even more fine-grained controls.
