Hi,
Following Google’s update to Widevine’s content decryption module (CDM) and encryption keys on May 31, 2021, Firefox users on version 87 and older may encounter issues with playing videos from streaming services with DRM. To address this, people should update to the latest version of Firefox.We generally recommend that people keep their browser (and any software for that matter) up to date.
