I am using Windows 10 64 bit and I am on Firefox 76.0.1 64 bit. VP9 will not hardware decode despite being supported by this GPU. I tested it with Kodi which was able to decode the video using hardware acceleration just fine. When I install the h264ify addon which switches youtube streams to h264 Firefox handles hardware acceleration with no issues.
