Steps to reproduce:
Forgive me for not really knowing anything about Mesa/OpenGL/WebGL/graphics drivers. On Debian testing (bullseye). Package libglx-mesa0 is on v19.3.3-1
Visit https://get.webgl.org/
Actual results:
get.webgl.org says:
Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.
in console:
libGL error: MESA-LOADER: failed to retrieve device information
libGL error: Version 4 or later of flush extension not found
libGL error: failed to load driver: i915
libGL error: MESA-LOADER: failed to retrieve device information
Expected results:
WebGL should be enabled.
WebGL works in chromium, and also works when setting security.sandbox.content.level to 2.
Also, I should note that this is not a regression introduced by a recent release of FF: it's broken on both v75 and v76, but oddly, was working just fine on the same machine last week. Possibly impacted by a recent Linux kernel upgrade (5.4.0-4 -> 5.5.0-1)?

https://packages.debian.org/testing/libdrm-common == 2.4.101-1
It should work (again) with https://nightly.mozilla.org.
