Having stuttering and lag. For firefox shut it down he said!

Developer Says;
Extension v2.0.* randomly working in background tabs?! Controls not visible on page load?!
I know... No need to report these issues again and again, I have never been able to reproduce them...
The only way to fix them was to rewrite everything from scratch to create the version 3.0, and after months of hard work it is now available for Chrome and Edge so install it on those browsers because the version 3 will only be available for Firefox if Mozilla changes its review process because after more than 12 years publishing my extension on AMO there are things that I don't accept anymore!

It's very nice but it makes youtube lag like crazy. I dont like using youtube without this but it lags to the point where if I close the window the video continues to play for a good few seconds after closing.

Edit: On FF This just abandonware at this point, should be removed from the recommended list.

You can use AI to make simple scripts to gain most of the functionality this brings.

Awesome i love this

It's great, but for some reason it doesn't always load anymore. I have to hard-refresh a couple times before it works again (i'm watching for the control buttons). when it does load correctly, it's great.

The extension is out of date. It causes youtube to be extremely laggy now. Even pausing can take several seconds.

Please UPDATE!

Läuft perfekt. Weiter so!

Please update.

¡Es la única extensión que logra forzar la reproducción con la resolución elegida. Siempre y cuando escoja 360 o 720, porque cuando fija 480 pero no existe la resolución, brinca a una más alta automáticamente!

this should be built into youtube

no seria de otro modo el efecto de esta app es maravilloso e infinito

Супер расширение. Один минус в яндексе перестал адекватно работать

Disabling autoplay no longer works, which was the only reason I installed this extension. Uninstalling now. Pity.
