Your WebGL is hardware accelerated (see WebGL Renderer). However, because we don't have hardware accelerated display of content on Linux, we have to read it back from the GPU and display it using software. That's what the "0/1 Basic" means.

Thanks Joe. Reading https://bugzilla.mozilla.org/show_bug.cgi?id=594876#c35 I had the impression it's fast. I'm getting 20FPS on Banana bread on an Ivy Bridge setup, which is pretty poor.
We need a better "sanity test" (acceleration on and off side by side would be nice) and a better indication of what's going (wr)on(g) that "0/1 Basic"... Should I file a new bug?

Nothing's wrong with your setup wrt accelerated windows; that's just indicating that you're not using OpenGL for composition, which is expected on Linux.

I don't quite understand. If I use "OpenGL for composition" (not sure functionality this exists), will that help accelerate Firefox performance?
