Firefox developers plan to block unsecured downloads on all HTTPS pages. Similar functionality was implemented in Google Chrome last year. It is also known as a mixed content download blocker.

The CA/B Forum team decided to clarify the rules for encoding domain names and IP addresses. Following discussion and voting, Ballot SC48 v2 was adopted by a majority vote.

If the changes are accepted, sites accessible via HTTPS will no longer have a lock icon in Chrome 93. At the same time, resources that operate over HTTP will continue to be marked as "Not secure".

The Firefox 91 browser, released on August 10, includes HTTPS by default in private browsing mode.

The CA/B Forum, the SSL certificates regulator, has decided to drop the subject:organizationalUnitName field because previous attempts to tighten its validation have been unsuccessful.
