Good point is it can download any video from many sites. Poor point is even though it needs compagnion apps, there is no explanation about that. It is very confusing.

Useless. 0/5 Stars.
Needs additional Program to do a job half as good as what other Add-ons can do without.
The long list of Permissions is a joke.

Most overrated Add-on here.
Doesn't deserve "Featured Extension"

This is just GREAT!!!! Now I can download videos from everywhere, which otherwise would have been absolutely impossible! I love this add-on!

ONE OF THE BEST SOFTWARE FOR DOWNLOAD

добър отзвук super ok Downloader

This is the very best video downloader I've ever used - I can't think of a time when I was unable to get the video I wanted, including those hard-to-get YouTube music videos! ★★★★★

prosty i działający polecam bardzo.

very useful.

A extensão é maravilhosa e muito simples de usar. Foi meu primeiro contato com extensão e já estou encantada. Ressalto que essa extensão no Mozilla é melhor que no Chrome

lekker handig, duidelijk.

It was already good, now they force an agent to download an application, to start downloading on youtube, even the android programs are better than he.

Já foi bom, agora obrigam agente a baixar um aplicativo, pra começar fazer downloads no youtube, até os programas do androide estão melhor que ele.

It's really awesome one which will work with almost with anything

Requires secondary program to enable SOME youtube downloads. Does not work on all videos. Watermarks all videos with ugly box. SLOW. EXTREMELY slow in combining video and audio files. To convert one 28MB file it took over 20 mins in Quantum Firefox 64bit. (On an 8 core I7). Uninstalling now.

Очень удобное дополнение! Много полезного и ничего лишнего. Загружает файлы быстро без зависаний.

Nettement moins fonctionnel que la version précédante

Very helpful and great add on when you get it working, i say that because depending on the download quality you select it may or may not work so you just need to find the sweet spot. Videos download without problem and its worth mentioning that if you choose quick download your downloads are not sent to the computers downloads folder rather a separate one under the app called "dwhelper".

Overall very satisfied

The only addon that's permanently working well with no issue since I started using it (more than 5 years ago, I guess). It's really hard to find a tube site that the addon doesn't support (however, a poor number of exclusive Youtube videos and some rare streaming sites have some tricky protection that results into an empty file download).
Awesome, useful and reliable downloader

Great.
