Firefox Nightly now reports unsupported CSS selectors. Since that fix was implemented, Firefox Nightly users can no longer log in into Cockpit, the login page just shows:
This web browser is too old to run the Web Console (missing selector(:is():where()))
This is due to a bad CSS capability check in Cockpit's login page.
