Details

(Whiteboard: [tor])

It would be good (especially for Tor) to support running without hardware WebGL, but without having to disable it.

On Windows this might be as easy as webgl.angle.force-warp:true.
On Mac this is bug 665630, which should be pretty easy.
Linux Mesa should be some fairly simple plumbing as well, unless there's no way to request llvmpipe.
I don't know if we can support this on Android, but that's not as important as having desktop support.

Ideally we don't expose the pref on platforms that we don't support.
