Firefox is causing loud fan noise and very high CPU usage. It is to the point I am going to have to stop using it.

Here is my info: iMac 27" 3.5 GHz Quad-Core Intel Core i7 16 GB MacOS Catalina 10.15.7

Increased usage happens when there are 3 or more tabs are open or any sort of streaming on one tab. It goes up and down, but reaches up into the 90% area.

There must be a fix for this. No other browsers have this issue.
