It is incorrect.
You can read the documentation: WebGL is on Firefox only activated for supported pairs of Operating Systems / Hardware.
You need to force the configuration otherwise.
Performance is decent with my Quadro FX3800.

If you have data to support it, please file a bug. 
I do not see this behaviour on my machines with Nvidia graphics so that would interesting to understand the difference.

I have seen a performance change with the last Nvidia driver update but I am still able to do 3d visualisation.
