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.

My Firefox was having issues with YouTube videos lately. It's double buffering at the start of video playback and seems to be stuttering on some parts, like skipping or going back a second. It only started happening with FF 96 updates.

I got so annoyed that it wasn't happening with my secondary GX browser. I started searching and found a thread leading to this addon and bam. It fixed the very problems i was having. No more buffering, no more stuttering/lag/skip, etc. Thank you so very much.
