Very, very useful. One aspect I would like though is being able to use the modifications to videos and that they would be applied when downloading the video.

ここまで素晴らしい機能補完は見たことがない

Edit: I am now having the exact opposite problem I had in the past. The extension only seems to work in private windows now.

Amazing extension however recently I’ve noticed that it no longer works when using in a private window. The … doesn’t appear anywhere, keyboard shortcuts don’t work and it doesn’t even automatically disable autoplay anymore (the extension still does shows up in the overflow menu though). Works fine in normal windows and has many useful features so I still highly recommend.

Fantastic add-on that works, has useful features and simple to use.

Muda totalmente a forma de assistir vídeos. Facilita a vida, mesmo para assinantes do serviço premium do youtube.
Só uma coisa que eu sinto falta: logo no começo, nos controles do player, para cada ícone aparece um "i', que mostra uma pequena explicação do comando. Esse recurso é bem útil e não aparece nos controles de volume.
