This extension counts exactly how much time you spend watching Netflix, even on a second screen.
Helps you keep track of how much you watch Netflix.
It counts exactly how much time you spend watching and shows a badge with the number of minutes you watched today. It stops counting when you pause, but keeps counting if you're playing in another window (e.g. on a second monitor).
