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.

even after installing this, youtube is still lagging. It doesn't work anymore.

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 does not work for anything over 1080P. Pretty much useless these days

при подключении этого расширения всё стало только больше тормозить, в других сервисах всё работает нормально, так что беда не в интернете

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.
