So much it's basically overkill at times. Never going back to watching YouTube without it. Basically ReVanced Extended for computers.

(see English translation below)
Extensão incrível que te coloca no controle de sua experiência em assistir/ouvir vídeos pelo YouTube. Super recomendo!
Algo interessante é o esquema de Exportação/Importação das configurações que economizam muito o tempo toda vez que fazemos novas instalações do Firefox.

Para ele ganhar um 10, só falta uma forma dos desenvolvedores implementarem uma playlist, como o NewPipe faz (www.newpipe.net).


Awesome extension that puts you in control of your YouTube video watching/listening experience. I highly recommend!

EfYT adds features that youtube should have by default. For some reason, YT choses not to give you the best experience possible. With EfYT, you get the best.

The latest update broke the volume boost functionality. On top of that, the volume is occasionally muted when starting a new video and I have to pause, mute, unmute, play the video to get the audio working again. And this often breaks audio sync so I'll have to pause/play again to resync the audio. But the volume boost is totally inoperative now.

This is a great YouTube extension, but after I use it for a long time it switches to Arabic, and all the Enhancer for YouTube buttons under my video disappear, then I have the reinstall the extension. Is there a possible bug fix for this?

awesome addon. ~ the only thing i'd like is: if you could disable youtube's new spacebar makes it fast forward instead of pause.
