I cancelled my subscription since I received a notification that my browser is not supported. Perhaps I should have mentioned my issues with DRM as well, but this may have gone too far. One message is clear, too many messages are noise.
Often with stuff like this, it still works when you clean cache and set your user agent to Windows and Chrome.
Would be curious to see if it works, OP.
The truth is that it mostly worked other than some issues with full screen but firefox has better ways around it. I really wanted to make the statement since I saw the notification that encouraged me to switch to another browser. Firefox is fully compliant and so should be their service. And should be DRM-free but that will be another discussion in the future.
