This is the only add-on that I've found that reliably lets me download YouTube videos in at least Standard Definition; most others only allow low-definition downloads, if they work at all.
Thank you for making this for us all!

aplicación muy buena

very good app for downloading videos

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! :)

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

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.

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.
