GLXtest error and H264 decoding support

I have a GTX750Ti card in my OpenIndiana desktop with the Nvidia Driver version 361.45.18 after enabling WebGL in Firefox 45.2.0 for Solaris x86 I was very happy with the WebGL performance.

When I entered about:support into Firefox, I obtained the following results

Adapter Description GLXtest process failed: VENDOR

Could Hardware H264 decoding be included in the driver and the GLXtest issue be resolved?
