Playing DRM-controlled content in Firefox

In Firefox version 47 and above, Firefox for desktop supports the Google Widevine CDM for playing DRM-controlled content.

Firefox downloads and enables the Google Widevine CDM on demand, with user permission, to give users a smooth experience on sites that require DRM. The CDM runs in a separate container called a sandbox and you will be notified when a CDM is in use. You can also disable a CDM and opt out of future updates by following the steps below. Once you disable a CDM, however, sites using this type of DRM may not operate properly.
Some sites may use DRM that is not supported by the Google Widevine CDM. Support for viewing this content may require a third-party NPAPI plugin, such as Microsoft Silverlight.
