Bernard Lheureux:
Since the last upgrade to firefox-60.5.0-2.el7.centos.x86_64 on my CentOS 7, it is no longer possible to watch Netflix with my Firefox, it always says that "Firefox is installing components needed to play the audio or video on this page. Please try again later." But nothing happens and Netflix is no longer readable with Firefox... I tried downgrading to firefox-60.4.0-1.el7.centos.x86_64 and al is now correct with Netflix... Anyone had experienced the same behavior ?
I think this might be something to do with an incompatible 'Widevine' plugin for playing DRM content
