(Firefox specific:) For testing purposes, visit about:config and filter for webgl preferences. Set webgl.disabled to true to simulate no WebGL. Also test with WebGL enabled but with webgl.min_capability_mode set to true, which currently inhibits display with a different error. Reasonable to treat both errors the same, but if possible try to get it working in min mode.
