Running Firefox ESR 68.6.1 on Xorg with intel I915 drivers. WebGL is detected in other browsers such as brave. Firefox does not detect webgl.

In some cases, your PC vendor will insist on releasing their own modified driver updates and there’s no guarantee they’ll do that. Your graphics card may be WebGL-compatible, but it’ll be blocked in Firefox if the driver version is 0.0.0.1 behind the approved list. Type “about:support” in the address bar and scroll down to the “Graphics” section at the bottom to discover whether your card is suitable.

Type about:config in Firefox’s address bar and make the following changes: 

   * To enable WebGL, set webgl.force-enabled to true.
   * To enable Layers Acceleration, set layers.acceleration.force-enabled to true
   * To enable Direct2D in Windows, set gfx.direct2d.force-enabled to true

Did you check the graphics section on the "Help -> Troubleshooting Information" (about:support) page ?
