Craig, that is a different problem, tracked by
https://bugzilla.mozilla.org/show_bug.cgi?id=1732580, and fixed in the
upcoming Firefox 94 (currently in the beta channel).
** Bug watch added: Mozilla Bugzilla #1732580

** Changed in: firefox
I upgraded my PC from 21.04 to 21.10. I found that WebGL doesn't work in
the snap firefox that 21.10 installed.
I uninstalled the snap firefox and installed the deb firefox via apt.
That fixed the WebGL issue.

Can anyone point me to where I can find the Firefox 82 debs? They seem
to have disappeared from /var/cache/apt/archives, and I really need
them.

The Firefox 84 WebGL section looks a lot like the v83 section:
HW_COMPOSITING
available by default
blocked by env: Acceleration blocked by platform
OPENGL_COMPOSITING
unavailable by default: Hardware compositing is disabled
WEBRENDER
available by default
disabled by env: Not
Despite it working in The Firefox 84 beta, the Ubuntu build that came
out does not work.

Alright, let's mark as fix commited, it's not likely we will try to
figure out what patches to backport and do another round of updates for
that fix before the new version is out so that will likely wait for the
next upload

If I were to speculate, someone tried to fix the "blocked by env" errors
in Firefox 82, in the process actually making that statement true with
some kind of fail code. In 84 they may have actually fixed whatever the
root problem reporting that message.

I can verify that the beta snap works as well, but I thought you said in
comment #2 that is a binary build straight from mozilla.

It's the "Acceleration blocked by platform" bits that are interesting.
It seems that message is there in v82 where it works and v83 where it
doesn't. The apparmor check seems relevant with that angle, I just want
to make sure that it's not something related to Ubuntu.

I just realized that the about:support output above is actually for
Firefox 82, which is odd, because it does work even though the output
suggests it shouldn't.
Here's a lot for Firefox 83.
The relevant section is different once again:

HW_COMPOSITING:

Thanks for the details Pat. Not sure what is going on, but it is good to
know that this is fixed in the upcoming firefox 84. Let's see if
upstream can shed some light on the problem in the bug report you filed
there.

I just realized that the about:support output I supplied above is from
firefox 82. I am confused by the HW_COMPOSITING section, when it clearly
works in v82.

Indeed, I downloaded firefox-84.0b4.tar.bz2 and WebGL works correctly in
that build.
On 84, compared to 83 above:

Here is the output of about:support. I suspect this is the relevant

I tried the snap and it behaved the same way, the exact same console

I assume by "xrg" you mean "xorg"? I have not tried under an xorg
Thank you for your bug report. What videocard and driver do you use?
Could you perhaps try if the firefox snap has the same issue? That's a binary
build from mozilla so it would help to figure if it's an upstream or packaging
issue
Did you try under an xrg session?
