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.

Took the CPU usage on youtube from 8-12% to 2-5% on a 5 year-old gaming PC. It really does wonders.

Works really well and as intended ! It made Youtube videos way smoother

totally fixed stuttering on youtube. even with a gaming PC VP8/VP9 causes issues

Great addon, thanks )

Works great.

Всем советую данное расширение, если у вас в видео на ютубе тормозит картинка, но при этом звук идёт нормально (у меня была именно такая проблема - с недавнего времени начала тормозить картинка на стримах, но звук шёл нормально). Перепробовал всё что только можно, и только это расширение помогло мне исправить проблему.

A very useful extension for those with low internet speed
