Firefox add-ons will stop working on March 14 if you don’t update
Firefox users running older versions of the web browser could be in for a really nasty surprise. On March 14, 2025, a critical root certificate will expire. And, if your browser isn’t updated to at least Firefox 128 (or ESR 115.13+ for those using the long-term support version) your add-ons will be disabled. Additionally, streaming services that require DRM may even stop working!
For anyone still using an outdated version on Windows, macOS, Linux, or Android, time is running out to avoid these annoyances. Even those sticking with older operating systems (such as Windows 7, 8, and 8.1, or macOS 10.12–10.14) need to at least update to ESR 115.13+ if they want to keep their add-ons and media playback working.
