Unfortunatly, there is no working.

Requires payment for mp3 download

Add-on requires a pay "pro" version to properly work. No trial version to even tell if it works. A "donation" is expected. Unable to verify quality.

Did not support any MP3 formats. Useless.

A marché la première fois, puis j'ai le message : "Youtube switched to separate audio/video streaming technology for higher quality formats and no longer provides direct 720p (Since 24 September 2018)/1080p/mp3 streams. Converting these streams to downloadable formats for you needs powerful server infrastructure, therefore 1080p/mp3 downloading has been limited to PRO users. Read more at - https://videodroid.org/pro_upgrade.html. FREE users can download all formats in CACHE where some PRO users fetched the video/audio in past 24 hours, to test the feature you can try downloading popular videos."
Donc impossible de télécharger une vidéo en MP3.
Semblerait il qu'il n'y ai pas de maj depuis 2018 donc ...

it doesnt work, uninstalling :(

doens't even work for 720p downloads anymore... useless.

реально не работающая фигня

Only VERY low quality downloads in the free version

Constant spam forcing new tabs open. If it was once a week sure, but it's at least daily.

stooped working a few weeks ago,loved it when it worked

gefaellt nicht, klappt so nicht und 100 Prozent Geld zurueck. war wohl nix

can not get any of it to work at all !!!

As of May 1, 2024, Google/Youtube, now knows how to block this extension, I am bummed, because I was able to download the videos, to by pass the forced brainwashing commercials! Please update.

Dead add on. Not sure why Firefox has this as a recommended When it doesn't work.

No longer works on youtube. Can't use 720p. Used to use it a lot but stopped working recently.
