Security and obscurity
So if the Chrome team's mission is to help users be secure, why has Chrome ca. 56 made it so much harder to view certificate details? Up until recently you could right-click on the "Secure" marker in the address bar and go straight to the cert - now all that gives you is a link to a generic help page, and you have to drill down into the Developer Tools UI to find this information.
In what world is this an improvement?
