Mozilla is reminding Firefox users that a necessary root certificate expires soon and that older browser versions could become a security and usability nightmare in a few months. Starting March 14, 2025, Firefox versions older than 128 (ESR 115.13) containing the expired certificate will likely cause “significant” issues with add-ons, content signing, and streaming of DRM-protected media.
You can use a custom config or soft fork.
Thanks for the tip! With the adware roll-out, I switched to LibreWolf. A pre 128 version of FireFox is my backup for sites that (are designed so they) don’t work with a more privacy-respecting browser.
Since no one has corrected me about which version the adware rollout started at, I interpret this move from Mozilla as a way to coerce/trick users into upgrading to a less privacy-respecting browser. I don’t want to crap on Mozilla too much, because they clearer are a lesser evil in the browser industry, but this is another move that erodes my trust in them. It’s too bad they’re moving away from their privacy- and user-respecting roots, as they were so great for so long!

Mozilla has been controversial as of late but they aren’t Microsoft. They want people to move to a stable release so they can stop having to maintain old code. Also modern Firefox has a lot of improvements and you need to use an actively supported browser to get security fixes.
