ça marche plutôt pas mal du tout. L'ergonomie est plutôt bien. ça prend pas trop de place dans la barre, et le choix des formats à la sauvegarde est très bien.
Après selon les sources, il faut parfois régler le format dans la vidéo pour avoir le choix de le sauvergarder. Et parfois non.

If there's a better downloader, I haven't found it.

Total waste of time unless you are willing to pay for their premium, the add-on simply doesn't work for YouTube currently unless you go out of your way to install the beta version, then in order to download it they make you install something else too, then finally they notify you only after downloading the video that "oh sorry we forgot to tell you we want your money so here is a QR code watermark that takes up 20% of the videos screen. LOOK ELSEWHERE.

It doesn't work

GOOD !!

I've had minor problems with the co-app and didn't use for awhile. but its remained one of the best extension of its kind, and works when many others have failed. go through the settings and pay attention and it will work for you.
EDIT: Sometimes you need to start the video first, other times you CAN'T. and other times you have to start it and select a resolution quality. mostly it's the first.

It doesn't work anymore. At all. I paid for the full version, and it hasn't worked for months.

Je l'utilise depuis plus de 10 ans, il enregistre à peu près tout, évolue avec les différents formats, l'appli est maniable, le suivi du téléchargement est visible avec les infos de la video en cours.
à mon avis c'est le meilleur enregistreur, de videos sans pub,
je suis très satisfait et je recommande vraiment!!

Tenho limite de download? Qual?

Download Helper has helped me save 100s of file that would have been a challenge to obtain otherwise. I am very happy with the product.

indispensable et si il pouvait capturer également les sous titres se serait exceptionnelle.
Bravo

This application is a very good way to download many videos. Unfortunately not working with some videos and the devs required some payment. It's useful overall.
