I just installed Firefox 56.0b10 (64 bit). Under Add Ons - Plugins, it shows "OpenH264 video codec.... will be installed shortly" Well, it NEVER installs.

How do I fix this?

This plugin is currently only used by WebRTC.

If you aren't using this service then there is nothing to worry about.

There is also the Widevine plugin used to play DRM protected media.

Does this plugin load or does it behaves the same way?
