A must if you still want to enjoy some of the media while offline.
Took some fiddling to get the extra thingy installed, but it works smooth and easy now.

excellents very good i loved

問題なくYouTubeから動画をダウンロードできます、それだけで十分です。
左下にQRコード入れられるのは少し厄介かもしれませんが、僕がいつもダウンロードしてる動画だと全然邪魔になってないので、5つ星です！

ちなみにMozillaさんはマイクロソフトやグーグルのようにわざわざこのアドオンのYouTubeから動画ダウンロードする機能に制限をかけるみたいな事とかしないのでそれもそれでありがたいです。

faz o trabalho rapidamente

これはいい

Can always do its job, and is a small lightweight extension too

New update puts QR codes on all the videos. Making this extension worthless

works ok until it forces you to download and install itself on your computer for larger media. kinda suspicious. Also now you need to pay or they put a watermark on the vid you downloaded.

great add on

genial

Doesn't work at all. Requires additional app even for basic work. Even after installing that app, it doesn't work and still throws errors.
