Comment (by keith768):

 It does work on Firefox 31 ESR. I've also reproduced the problem on
 different windows versions (7, 8, 8.1...) and different hardware. So it's
 safe to assume it's not OS or hardware related.

 Under the "Graphics" section it indeed shows different information between
 Tor Browser and regular firefox:
  1. DirectWrite is false in Tor Browser
  2. "GPU Accelerated Windows" is "1/1 Direct3D 10" on FF and "0/1 Basic"
 on Tor browser.
  3. AzureCanvasBackend is skia on Tor Browser, direct2d on FF.
  4. AzureContentBackend is cairo on Tor Browser, direct2d on FF
  5. Most important of all, the line of "WebGL Renderer" is completely
 missing on Tor Browser.

 The rest of the section is identical (driver versions and all).
