Reported as seen, and WebGL can't start by default.
So defaults need to be changed then for an user to be able to use WebGL.

WebGL test page:
https://www.khronos.org/registry/webgl/sdk/tests/webgl-conformance-tests.html
If it says
"This browser does not appear to support WebGL "

According to
https://support.mozilla.org/en-US/questions/720087

In   about:config  in Firefox, searching for 'webgl'  ,
both webgl.disabled should be set to false
and webgl.force-enabled   should be set to true

Also , graphics card can be disabled in:
about:support , under 'WebGL Renderer'

So check if you are using Noscript, that also blocks WebGL by default
and enable it with
about:config , noscript.forbidWebGL should be false
(I don't know if Noscript should enable WebGL for enabled sites, but
this chack makes it working).

Now I was toing per-userland consolidation testing in those days,
but now I cloned with beadm old BE's form April and even with fresh
emptied user home dir, I get same 30-50 CPU use , so from before moment
in time when mesa got updated.
(same with mesa freezed to pre-update .1 version and then updated,
problem is still there, so doesn't seems that is the only problem.

I could be to have something between 9500GT and Nvidia drivers and illumos
or it is System Monitor itself, becasue prstat and top doesn't show
large CPU use, so some Dtrace could be in line to figure it out..
