If you can reproduce this, please try to grab a performance profile with the Media setting enabled. The generic profile doesn't have much information for us to go on.

Hello, Jim.

Check if this is the correct profile: https://share.firefox.dev/4kR8GWN

Looks like gc triggering occasionally, and that causes jank. Oddly though I don't see a reason for it.

From this profile, what I see is the media was paused around 2m32.7s and then it got shutdown later. If I assume you didn't trigger that pause by yourself, then we would need to find out where did that pause come from. Could you follow this instruction to capture a media profile which can give us more log information?

In addition, how constant this issue would happen? would it always happen after a certain time of playback? Would it happen on a private browsing window? Thanks!

Apparently, I am not able to reproduce the problem anymore. The stream is working as it should.

In addition, how constant this issue would happen?
Every time I entered a stream in twitch.
would it always happen after a certain time of playback?
There was no pattern.
Would it happen on a private browsing window?
It would happen both in regular and private browsing.
