Eurosport Player tab leaks memory
I don't know how to make this easier to reproduce, because Eurosport Player requires a subscription. While a Eurosport Player video is streaming, Firefox memory usage increases by approximately 50 Mb each minute. In about three hours, Firefox becomes less responsive and its CPU spikes every few seconds. Doesn't happen with Youtube or Twitch.
I'm on Windows 10, Firefox 90.0.2.

That is, its CPU usage, not its CPU.
