> This seems like such a contrived scenario Agreed. I suspect the number of people assisted by this button is vanishingly small, and outweighed by the number of people who don't get the information they're looking for because they accidentally click the button and can't find their way back. Or the number of people harmed because the "exit this page" UI is on some pages only (for example, it isn't here on HN), and that is even more confusing for users who aren't tech savvy enough to realise its part of the site not the browser and who could come to rely on it. Overall, I think this button is poor UX and shouldn't be used, even on pages with sensitive content that it is intended for.
