Hello, I saw on the forum that you have had request for the same issue dating for more than 2 years ago, My question is, Are you planing to add Cast on your addons library so i can cast from Firefox and not Open Google Chrome only for that option while i like Firefox more for the more practical usage it has for me, Hope someone will read this and think to do the requested update, while i am sure i am not the only one who needs it, Kind Regards, Agron
