> Does MOZ_ACCELERATED=1 alone work?

Yes, "MOZ_ACCELERATED=1 firefox" does work but I can not see any
performance improvement compared to a mere "firefox" while running this:
https://webglsamples.org/aquarium/aquarium.html
I get stable 36 FPS while none of my CPU core seems full (CPU usage
reported by "top").
"chrome" gives me stable 59-60 FPS with comparable CPU usage while running
the same WEBGL sample.

> Can you check WebGL2 in about:support?

I copied and pasted the relevant output:
