Maybe it used to be good, but it now requires payment to download as mp3 (and some video type(s))

1080p not free

An automatic update today, rendered my down loader useless. I've enjoyed it for a long time. What can I do? Do I have to pay more money?

This addon will pop up a new tab every couple of days while your trying to beg you for money, there is no way to stop firefox launching and going to this new tab, I've had virus's which were less invasive. Avoid.

Annoying popups every time it updates.

Бесплатно не работает

Shortcuts don't show up under the video.

Can't get fullHD video

Pay only, I wouldn't give a one star rated if they warned about this at the time of downloading, you only know this AFTER you downloaded and installed it.

Debería indicar bien visible que está limitado en funciones al no ser que pagues por él.

expensive

Fonctionne plus mais pour demander une cotisation ca fonctionne !

EDIT: Unfortunately this once great extension is now defunct. The author doesn't seem to keep it updated anymore. Don't bother with this. Grab "Video DownloadHelper" instead.

The best youtube downloader extension, period. I'm a tabletop RPG GM and I use music from video games for my sessions a lot and the music is hard to find sometimes. So it's easier to just go on youtube and do the conversion myself. The person maintaining this extension is very diligent in updating it too. 5 stars!

i had installed this add-on and it worked. a few days later, i was working in my bank account and a new firefox window auto-opened. i thought it was a virus. this add-on had opened it and was "updating" me on issues with the add-on and requesting money. when i tried to close this auto open firefox window, it popped up a "buy me a coffee" box, which i had to manually close before i could close the window. basic virus behavior - auto opens with a popup while i'm in my bank - c'mon man. immediate uninstall. also, not very comforting to know that firefox let's it's addon programmers do this. if firefox allows programmers to do that, they could have access to everything on my machine. awful stuff.

Раньше было отлично,теперь не работает

It seems that all they want is donations, over and over and over again. And their support is a joke.
