Hello,

I think I'm observing similar issue on my computer.
Scenario:
- Open twitch.tv/{any_channel}
- Keep the stream open for some time.

Observations:
- Hight memory usage by content process associated with the twitch page
- Process Explorer: https://imgur.com/a/OoQHnaX (memory dump of the process: https://1drv.ms/u/s!AhwtP-L46eEngYgn8o4NN06SDpKo7A)
- Gecko profiler log: https://1drv.ms/u/s!AhwtP-L46eEngYgozIcX0jBbCnEsLw
- Screenshot of 'about:performance' page after ~45min: https://imgur.com/Gh9pCv3
- Screenshot of 'about:performance' page after ~60min: https://imgur.com/zjQFpJM
- Highest I observer was 1.7GB by that process

Hope this helps :)

Yeap it happens for years now. If my regular memory consumption for Firefox about 800mb after about 10 minutes watching twitch it raises to 2.5gb!

Twitch didn't done anything about it yet, here is how "Chrome" world looks like. 😞

Actually I think the issue comes from a twitch chat. The more chat activity, the less time it takes.
