使いやすくていいものです

great app

The best available downloadhelper

haven't used it yet

The only good download helper for Firefox

Works pretty well, sometimes it sticks. I do enjoy it.

muito bom

Ne fonctionne pas toujours, je cherche encore à la faire fonctionner !

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!

My first (& last) download was damaged because I was'nt registered! You didn't have to force me to register! If it was a good app, I would come for more....

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! :)

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