Mozilla closes support thread 2 days before baked-in CA TLS certs expire (mozilla.org)
Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

Practical HTTPS Interception: 20 Years of SSL/TLS Interception (thc.org)
TL;DR: An attacker can trick Let's Encrypt (LE) to issue new TLS certificates for any domain that the attacker intercepts traffic for. The attacker can then decrypt the TLS traffic. This one thing that TLS is supposed to prevent from happening. The fault is that LE uses cleartext HTTP to verify the ACME-challenge (which the attacker can intercept).

Ten Years as a Free, Open, and Automated Certificate Authority (fosdem.org)
People deserve a secure and privacy-respecting Internet. Ubiquitous HTTPS is an essential part of delivering on that vision. To that end, our public benefit certificate authority has been issuing TLS certificates free of cost in a reliable, automated, and trustworthy manner for ten years. We went from issuing our first certificate in 2015 to servicing over 500,000,000 websites in 2025, and we’ve got big plans for the future.

Six day and IP address certificate options in 2025 (letsencrypt.org)
This year we will continue to pursue our commitment to improving the security of the Web PKI by introducing the option to get certificates with six-day lifetimes (“short-lived certificates”). We will also add support for IP addresses in addition to domain names. Our longer-lived certificates, which currently have a lifetime of 90 days, will continue to be available alongside our six-day offering.
