This add on helps me everywhere

video downloader has worked really well for me. But recently you tube videos are not offering formats that I can use anymore.

Have used it for years. It works quite well, in spite of websites frequently changing code to disallow video downloads. I highly recommend this mature, working, safe, reliable add-on. This alone makes firefox my browser of choice!
Update: I've now used it for another year and the active development is a great feature - when a site blocks downloads within a short time Video DownloadHelper is modified and works again. This is great software.

Muy buena. Nunca tuve ningun problema.

利用して数年？のおっさんです。使用時の設定がなかなかうまくいかないのでそこだけが少し不満ですが全体には満足しています。

positivissimo buonissimo

Perfetta in tutto grazie

Sehr gut und einfach zu bedienen. Danke schön!

Очень, удобное дополнение, работает на всех сайтах))

Simple et efficace

I have used a number of down loaders and Video Download Helper is the best. It works every time for me on the site I visit.
