Am I to take the "Toggle the Primetime plugin to Never Activate" to mean that the Primetime plugin is no longer required for this? The other issue is that I don't see media.gmp-eme-adobe.forcevisible in about:config, is that to be found somewhere else? Someone said that they had to disable the Youtube Flash Video Player extension, which I'm now using to force the use of Flash on Youtube for reasons that are too long to go into and have to do just with the Youtube player interface. Would I have to disable this extension? Also, I have the problem that twitter and periscope videos don't play in FFox or Opera but DO play in Chrome. Does anyone know how to sort this out in Opera?
