need just 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!

Ohh nooo. If you want them to see everything you do in your browser, including user name and password for Where ever you are are. Go right ahead and install this.

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.

I used this extension on Opera, Brave and it was OK, but in firefox it makes youtube be laggy

It will work but just so you know, this addon removes the settings for above 1080p video quality (like 4K).
It also seems like it has been abandoned by it's current author.

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.
