Thanks, that (about:config webrender) has reduced the processing. What's
puzzling though is in Firefox settings it has:

[x] Use recommended performance settings
Learn more
These settings are tailored to your computer’s hardware and operating system.

And when I uncheck the box, it shows hardware acceleration enabled. So I

wondering if the light is on in the fridge when the door is shut.

My GPU is:

Integrated Graphics Controller (rev 0b)
