Probably due to the release of WebGL 2 in bug 1232864.

After changing about:config browser settings:
  webgl.force-enabled=true.
  webgl.msaa-force=true.
  layers.acceleration.force-enabled=true.
  gfx.direct2d.force-enabled=true.
point cloud are available in potree renderer for Firefox 46.0 and Firefox Nightly 49.0a1.
