Firefox [new] | Widevine

Mozilla’s most significant contribution to the security of DRM implementation is its sandboxing approach. The Widevine CDM is closed-source; theoretically, it could contain vulnerabilities or malicious code. To protect the host system and the user, Firefox wraps the CDM in a strict sandbox.

Mozilla initially resisted implementing EME due to concerns regarding the open web and the potential for proprietary lock-in. However, the realization that a failure to support EME would result in a mass migration of users to proprietary browsers forced a strategic pivot. In 2014, Mozilla announced its intent to implement EME, but with a unique architectural approach designed to mitigate security risks and adhere to its open-source manifesto. widevine firefox
