Use to be able to record livestreams with this add-on. I can still record using the companion app which is a seperate download but for some reason with the firefox v57 quantum update you removed the STOP button which normally would save the recording as is when you hit it. Why was this done? Now I can no longer stop a live stream recording and save the video. If I exit browser during a live stream it results in a file that cannot be played. Can you please add the STOP button back to the live stream recording companion app?
