 Actually not NPAPI which would not be much of a problem. So, currently
 this would only affect GMPs but that's a thing we don't support out-of-
 the-box either. We don't want to have DRM GMPs and the OpenH264 one is not
 useful as we are disabling WebRTC.

 That said Mozilla wants to get away from `SANDBOX_EXPORTS` as well, so
 this seems not a bad direction to move in and allows us to use our scarce
 resources somewhere else.

 If anybody wants to investigate the underscores issue, please do. I'd like
 to know what's up with that one.
