enhanced-h264ify is a fork of well-known h264ify extension for Firefox/Chrome which blocks VP8/VP9 codecs on YouTube, so that you can use H264 only. This may be useful because there are lots of devices on the market which support H264 hardware decoding and do not support VP8/VP9.

This extension has new features such as manual blocking of H264, VP8, VP9, AV1 codecs and 60fps video. By default it blocks everything but H264 and 60fps video. It works only on YouTube. GitHub: https://github.com/alextrv/enhanced-h264ify

Thanks to this plugin I was able to resolve iGPU heating issue on MBP 16 2019 which is not capable of natively decoding AV1 content. I needed to disable only AV1 and keep VP9 so I still can play 4k 60fps content.
