Often, because of various reasons (mostly to show other people a webpage to view or edit on which requires some sort of setup or login), I need to give people physical access to my fully unlocked laptop. That means they can see my browsing history, and I don't want that to happen due to privacy reasons. I already have a script that allows me to stop the Dock process (thereby eliminating the ability to navigate to other applications except the current one), so other application is not a concern. How can I temporarily disable access to view history or protect it with password without having to restart Google Chrome?
