Не выбирайте ADP из списка форматов при скачивании. Тогда загрузка будет быстрой и при воспроизведении не будет QR-кода.

Trying to download anything from Youtube tells you you have to install their companion app for it to work. Rubbish, other addons download the mp4 no problem.

O melhor, The Best, não tem outro mais fácil e rápido, eu recomendo de olho fechado.

Melhor extensão para baixar vídeos da internet. Recomendo!

Мало того что нужно отдельно скачать дополнение к дополнению, так ещё и ЦП грузит под 100%

great add on can download off web sites without joining them

使用起來方便性不錯，很值得推薦！
讓下載影音變得很方便！
感謝開發者！

Easy to work and always good results. If I wasn't retired and on a limited fixed income I would send you guys some bucks--Sorry I can't.

Sketchy, doesn't actually download anything unless you download a companion app. No thanks.

できたりできなかったりするけど、おおむね満足

Es uno de los mejores complementos que puede tener firefox, es genial, yo lo utilizo en linux y marcha de maravillas
