Firefox seems to use a lot of CPU capacity. I often notice the cooling fans running. Why does a browser need this much CPU? Is there something I can do to fix this?

I have attached a screenshot of CPU usage according to EtreCheck.

I am running OS X 10.11 6 on a mid-2015 Retina MacBook Pro.

Thanks for your assistance.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?
