Update 2024/APR:
Still a great, great, great add-on!! Still loving it! :)
I was happy to make a donation, and will donate again.

Update 2022/NOV:
still loving this addon!
Doing exactly what it is supposed to.
You can also download just MP3s.
Keep up the good work!

Add-on actually works. :) As of 05/AUG/2019
In the free version, you can download 360p MP4s. After a one-time payment, higher quality videos and mp3s are available. VERY WELL WORTH IT! Excellent add-on!
Thank you so much!

its so good

Unverschämte Berechtigungsforderungen. Nein Danke.

Don't bother to download, does not work if you don't pay for the pro version, waste of time here...

I hate when they dont inform users that you have to pay them to get the app to have the funnction at all!

To be very frank, the people down voting this app are dumb af. I have downloaded YouTube videos in the past and it was super easy but lately it has been getting harder and harder for OBVIOUS reasons!!! I tried a number of apps and had a very frustrating experience. This app is 99% effective as far as I can tell and I have no complaints. Rarely it will fail to find a high quality file ( likely due to only old source file at lower quality available). I will be back to donate again if the service remains this good.
V impressed!

It's nonsense that a "powerful server" is necessary for downloading a youtube video.

I've been downloading for years with other add-ons that don't use another website's "converter".

I downloaded the youtube downloader and it gave me a PDF converter. On top of mozilla disabling my youtube downloader form unknown reasons, your performance is horrible

Might work, but requires you to buy a pro version to download any videos.

I have tried every single youtube downloader addon (wasted hours) and this is the only that works easily, well, and consistently. If you need higher quality >320 and 96kbps audio (which I do) just pay him the small $ fee and get that feature. Well worth it!
