I'm having trouble understanding why h/w acceleration is not supported for my graphics card. I have an 'Intel(R) G33/G31 Express Chipset Family' internal card. Firefox says 'Blocked for your graphics driver version' under troubleshooting information. I'm running Firefox 18 beta under Win8x64. So, here's the trouble. When i was running Windows7x64, h/w acceleration was available only under chrome & that was limited too. I never really complained because i understood my card was about 5 years old. When i moved to Windows8, i was planning on getting a new graphics card, but to my surprise Intel had released new drivers for this version of windows & suddenly i was getting full acceleration under IE & Chrome & Adobe flash is also playing h/w accelerated videos. It would be helpful if someone could tell me why only Firefox seems to have a problem.
