Yes, I'm up-to-date but in my experience Firefox has a worse WebGL implementation than Chrome. Didn't try with Chrome. I also have a not-so-great CPU (but a high end GPU) so that affects too. In any case, my computer is able to run quite high end games, it should easily be able to run a simple terrain demo if it weren't for the overhead. There's certainly different performance characteristics in different OpenGL implementations (ie. GPUs) but WebGL overhead comes on top of that. So in addition to the performance characteristics of the GPU itself, you have to think about the browser's software implementation too. WebGL is definitely a welcome addition to the facilities available in the browser, but getting more up-to-date features would be nice. And using the security features (especially bounds checking) of the hardware if available to avoid unnecessary overhead would make it a lot more appealing.
