(AUS was down for 3 weeks once, and that stopped new installs of Firefox from being able to play Netflix, which is why we have this fallback path for GMP/CDM downloads). If the download of the plugin list from AUS fails, we'll use the LOCAL_EME_SOURCES list to find a location to download the plugin from.

Let me know if I should file a bug for Firefox. But as it looks like it is `` which has to be set: Personally I would only expect to have to set `` to `false` to stop all downloads. There is something really wrong here in Firefox I assume. So why does disabling EME not also disable the openh264 plugin? Also I can set '' to an empty string or '' to false, but Firefox always downloads this plugin. Interesting that the addon manager repository lists all of the above mentioned plugins as EME: > For EME plugins we basically need another pref which is ``.
