In the nightly builds of Firefox, which will form the basis for the release of Firefox 75 scheduled for April 7, the design of the address bar has been updated. The most noticeable change is the display of the https:// protocol and the subdomain 'www' in the dropdown link box that appears while typing in the address bar (for example, content-differentiated https://opennet.ru and https://www.opennet.ru will become indistinguishable). The http:// protocol will continue to show up in results unchanged. The display of the URL in the address bar will also remain the same.
