Updating Browsers and Widevine CDM

In late 2024, Widevine ceased support for certain versions of browsers and OS (operating systems). Widevine is an encryption framework offering DRM solutions to secure high-quality videos and audio.

Supported Browsers and OS Versions

MUBI supports the newest versions of Chrome, Firefox, Safari and Edge on Mac & PC. Please see mubi.com/devices for a list of our supported devices. Linux users must use Chrome.
