Overview
Product summary
Review the store description, core capabilities, and common use cases.
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, Opus, AAC codecs and 60fps video. By default it blocks everything but H264 and 60fps video.
It works only on YouTube.

Tremenda obra maestra. Mi laptop y yo te lo agradecemos, GRACIAS!!!!
Works great as it is, does what it says perfectly!
Good but you should rename it to block/enhanced ytb codec I'm using it to force av1
Doesn't work
Dios bajo y nos dio esta extensión
I have no idea what this extension does, but since I installed it on my Windows 10 PC to try to cut down on YouTube running my CPU usage up to 100%, the CPU usage of Chrome is 4th or 5th on the Task Manager meter. Right now I am running a video on YouTube and streaming a hockey game, and Chrome is using only 0.9% of the CPU. To me, this extension is the best thing since Windows 7 (RIP) and sliced bread.
Blocking 60fps on Youtube works.
it removes higher than 720p but it can remove 60 fps i get nousious watching minecraft video's at 60 fps but 480 looks really bad now i can watch at 720 andf this is good for me
An amazing extension. Works as described. Thanks dev 🤍
