This did not solved my issue. Disabling hardware acceleration fixes the canvas bug.

Well lists your drivers but no card, I would guess older. Issues : failures: [u'CP+[GFX1-]: Failed to do glGetActiveAttrib: 1282']

Try a refresh, about:support then click "refresh firefox". Also if your on the nVidia webdrivers make sure to update to the latest ones after each OSX update, sometimes you got to wait a day or so...

That did not help either. I downloaded version 55 and everything is working fine (56 has the same issue as 57).

Firefox 55 reports WebGL 1 Driver Version as 2.1 NVIDIA-10.29.10 378.10.10.10.25.102 while version 57 reports as 4.1 NVIDIA-10.29.10 378.10.10.10.25.102, so a different OpenGL version is used.
