Firefox WeGL issue

Hi all, since about 1 week ago (probably the update to 75.0.1) I’m getting messages like “This app requires a WebGL-enabled browser to run” in Firefox.

I’ve checked about:config and I see

webgl.disabled is False
webgl.enable-webgl2 is True

same site works fine in Chromium.

any ideas on how to solve this?

Hello @Amsterdam4572

Install: mesa-demos
Run: glxinfo | grep OpenGL

See what that gives you after.

Now you try the site and see?

no, still same problem. Even made a new Firefox directory on my home drive

ah ha solved it with help from https://www.reddit.com/r/firefox/comments/fxltkx/webgl_not_working_in_ff_75_in_linux/

security.sandbox.content.level set to 2, not 4 allows WebGL to work again.
