I'm using Firefox on a Windows 10 PC. When I'm on FOXNEWS website and every video opens a new window and automatically starts playback. I'd love to be able to change this option to be optional instead of being automatic. With the last update, all the video playback windows now have 'NO CAPTIONS AVAILABLE FOR THIS VIDEO" displayed at the bottom of every video playback window within a semi-black band with yellow lettering. You can not stop this annoying msg from being displayed, so it stays up during the entire video playback. I've searched FireFox and can not find an option to fix this. Please advise...
