As of Firefox 58.0.2, I can reproduce this problem at https://shaka- player-demo.appspot.com/ too. Looking at the "Asset" dropdown on that page with the Ubuntu-provided version of Firefox, various DRM-related options are grayed out, including the Widevine options. With the downloaded-from-Mozilla version of Firefox, the Widevine options are available.

Specifically, if I go to https://bitmovin.com/mpeg-dash-hls-drm-test- player/ with the Firefox 56.0 included with Ubuntu 16.04, the video box in the middle of the page displays static with the error message "DRM: Failed to create and initialize a MediaKeys object". If I instead download Firefox 56.0 from https://ftp.mozilla.org/pub/firefox/releases/56.0/linux-x86_64/en- US/firefox-56.0.tar.bz2 and extract and run that Firefox, the video will correctly start after I click play. In both cases Firefox is configured with: * about:preferences > "Play DRM-controlled content" checked * about:addons > "Widevine Content Decryption Module provided by Google Inc." v1.4.8.1008 installed and set to "Always Activate" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1724705/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
