It just leads you to a website. Which doesn't work. LOL. I feel suspicious of this. I do not recommend this add-on.

垃圾

The downloads keep failing and won't resume.

Не работает. Какое-то нелепое окно в трее браузера появляется и все

Not working.

This product started out working fine, now, suddenly, it has completely stopped. Perhaps it was the upgrade to FF V63.0.3? But anyway, it is now totally useless.

It dont works

Działało poprawnie przez bardzo długi czas, teraz już nie radzi sobie ze ściąganiem mp3 z youtube.. szkoda, bo było bardzo proste w użyciu i, jak niewiele konwerterów mp3, oferował jakość 320kbps.

This add on worked great at first but now it doesn't work at all. I hope that you can fix it soon.

otra aplicacion que no funciona---- perdida de tiempo

Complete garbage. Doesn't work at all.

Garbage. It worked great 3 or so weeks ago. Now this:

error in server response please try again
Failed to retrieve video data 1537002219 https://www.youtube.com/watchblahblahblah

Works for about 30 percent, fails for the rest. Make things work and get donations. Simple. I'll contribute when this simply works...

Why does it need access *to all my websites and browser activities? It's like selling oneself to ALL spammers and commercial giants on the planet!!! That's absolutely unacceptable!!!

Extension is not working. Stalls at "Download Started" In the past have emailed developer and they have made the fixes. I always check to be sure the extension is working before I donate. I emailed developer with the explanation of what I was encountering in trying to use this. Nothing is happening. Does anyone have another safe Youtube to MP3 converter that doesn't load malware or ads.? Got this to work one time but download was extremely slow!

primero añade y acepta y no aparece nada y su pueden decirme porque no puedo bajar videos de you tube a mi pc hoy 20 de septiembre 2018 no se puede acceder a you tube desde firefox para bajar videos a mi pc?

I tried 15 different videos and each time I get an error:
"error in server response please try again
Failed to retrieve video data 1536656441"
then stuck in death loop of bs

just up and quit working. I have scrubbed my system clean, uninstalled and reinstalled the app.
Went form a 4.5 to a 1 very quickly.
