Update Firefox to prevent add-ons issues from root certificate expiration - lemm.ee

> On March 14, 2025, a root certificate [https://en.wikipedia.org/wiki/Root_certificate] used to verify signed content and add-ons for various Mozilla projects, including Firefox, will expire. Without updating to Firefox version [https://support.mozilla.org/en-US/kb/find-what-version-firefox-you-are-using] 128 or higher (or ESR 115.13+ for ESR [https://support.mozilla.org/en-US/kb/firefox-esr-release-cycle] users, including Windows 7/8/8.1 and macOS 10.12–10.14 users), this expiration may cause significant issues with add-ons, content signing and DRM-protected media playback. > > If you don’t update, Firefox features that rely on remote updates will stop working, and your installed add-ons will be disabled. DRM-protected content [https://en.wikipedia.org/wiki/Digital_rights_management], such as streaming services, may also stop playing due to failed updates. Additionally, systems dependent on content verification could stop functioning properly.
