Chad,
I think the reason is that the depth_texture extension is missing on your
config.
On my Mac (Intel HD4000) the following 2 extensions show up in FF 27:
WEBGL_depth_texture
GL_WEBGL_depth_texture
Could you check whether FF Nightly lists these? It's a bit strange that
such a common GPU (NVIDIA) wouldn't expose depth textures. I'll have to add
at least a warning if the extension couldn't be found.
Thanks!
-Floh.
