User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0
Steps to reproduce:
Upgraded from 86.0.1 to 87.0, instantly noticed huge lag issue in Twitch player when I had two streams opened at the same time.
Actual results:
CPU jumping from 24-35% usage on Intel i7 3770.
Expected results:
When I downgraded back to version 86.0.1 and did the same thing CPU usage is from 9-15%. So I would expect the usage to be the same or better on the new version.

The Bugbug bot thinks this bug should belong to the 'Core::JavaScript Engine' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

A Firefox Profile would be enormously helpful to point this to the right component.
If you have time, from both old and new would be helpful.
I am also experiencing this bug. I'm running Firefox 91.0 on macOS 11.5.1
