I just discovered this after my other extension to block 60fps on youtube stopped working. This works flawlessly thank youuuu

immediately fixed my problem with lag on youtube

only need one word *amazing

h264ify is a must-have for smooth video streaming. It's like a magic wand for your browser. No more buffering or lag – it just works. Love it!

Thanks

Super.

This addon is amazing. Before installing, I could barely get over 5 fps with 720p videos. Now I get smooth 60 fps with 1080p.

en una PC de poco recurso sirve.

Fixed youtube high CPU usage. I think Mozilla should add this extension to recommended ones.
PS. For your knowledge the max resolution you will get using this extension is 1080p.

fixed the long-time issue with youtube stutters/lags over time

this is absolutely amazing.
