"Some sites hide their players from extensions."

The add-on was perfect, it was just working last night. I was appreciative of the service, and I still am. But now it doesn't work on any of the sites I need accessibility adjustments for. Why is there no way to override? What is the point?

I don't understand what the point of the great UI improvements, sounds and visual effects if you've reduced the core functionality of the extension? The privacy assurance is the reason I chose this extension over others, but if it doesn't work then I have no choice???
