Scatter_matrix demo page does not render correctly on Firefox 79.0 (Linux)

For some reason all the real content is missing on my browser here:

Other plotly pages work OK!

Looks like it could be an issue with webgl, does this website work? do the 3D chart types work?

Thanks, I had to set webgl.force-enabled for some reason! Works now! That page should probably tell when WebGL is missing…?
