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.
