Firefox on Mac (a lot of tabs) is constantly on top of CPU usage. How can I discover which tab(s) is/are resposnible for high CPU usage ?

I have a lot of Firefox windows with multiple tabs in each (this is my way of working ...). I can see in the Activity Monitor that the Firefox is the most active application in terms of CPU and energy consumption on my Mac (it just drains battery ..). I used the Task Manager but it doesn't help much. Is there any better, more detailed way how to display which tab could be blamed for CPU usage ?

Hello p5555,

As neither the Activity Monitor nor the Task Manager give you what
you're looking for; would you try this please :

Type in the address bar about:performance and press Enter.

You could also try about:memory.

Any good ?

But Task Manager is the same as about:performance, isn't it ?
