Is this broken in Firefox? I just see a black square in the top right.

WebGL disabled? Devs really need to get better at notifying the user instead of just crashing.

In about:config all "webgl" settings are their default values.

Works for me in mobile Firefox on Android with ublock origin and umatrix. Everything loads and I can make the little robot do backflips and stuff. And I usually get WebGL issues with this set even before the plugins come into play.

Huh, no idea. On Windows 11, no WebGL custom settings.

Works fine on 152.0.5 (aarch64) macOS 26.5.2. I don't use extensions like NoScript etc etc
