Despite plenty of opposition, Google has stopped showing “www” and “https://” in Chrome 76. Users who want to view the full URL can do so by double clicking on the address bar, but the subdomains will likely be hidden by default going forward. (This is actually the second time Google insisted on the change, with the first being Chrome 69 back in September.)
Chrome users who don’t want “www” or “https://” hidden can also disable a flag (chrome://flags/#omnibox-ui-hide-steady-state-url-scheme-and-subdomains) to revert the address bar to its previous behavior. The Suspicious Site Reporter Extension can do this, too.
“The Chrome team values the simplicity, usability, and security of UI surfaces. To make URLs easier to read and understand, and to remove distractions from the registrable domain, we will hide URL components that are irrelevant to most Chrome users. We plan to hide “https” scheme and special-case subdomain “www” in Chrome omnibox on desktop and Android in M76.”
