I my opinion this is still the best video-downloader for any browser out there! If everything else fails (JDownloader 2 etc. included), I come back to firefox and this addon just does the job.

A big THANK YOU! :)

Only detects 5 out of 63 videos in a YouTube playlist. Confirmed useless cos other video downloaders detected all 63.
WTF?

Excellent add-on. Very easy to use, no advertisements.

useless, doesn't do anything but asks to install additional program.

夥伴軟體用人家開放源碼的東西來營利，感覺不是很好。

Molto efficiente. Unico piccolo neo: quando scorro fino in fondo all'elenco dei video per cliccare su quello da scaricare diventa un po' scomodo. Dovreste abilitare l'opzione di visualizzare in cima all'elenco i file più recenti (se non è già prevista... io non l'ho trovata).
In ogni caso programma fantastico!

Please, insert the option that can permit a visualisation with the most recent files at the top of the scroll

Works awesome for me.

Good Software i dont understand the alternativ software installer is then safe ?

Tolles Tool.
Nach updates funktioniert es jetzt super.

Update: Auch nach 2 Jahren bin ich von dem Tool begeistert.

excellent add on works perfectly, no annoying ads or anything to mess up a downloaded video

It works. Helps studying and reinforcing concepts.

Good extension. No more words.

Sehr hilfreich und zuverlässig.

Отличное приложение, советую, перепробовал много других, но лучше пока не нашёл.
