Regretably this app has not worked for some time and there seems to be no updates happening. When you click the button it just sits on generating link and does not progress any further. Shame as it was a damn good app. There is no way to contact the dev to ask what's happening.

Presque tout est bloqué derrière un paywall meme le mp3! passez votre chemin

Does not work at all.

No longer interesting, as it has locked the most useful features behind the PRO version.

Why is still "recommended"? Mozilla what's wrong with you?

Nic za darmo, wszystko za pieniądze.

LIXO ... Quer cobrar por tudo

As my User Account name says, I'm using a relativly expensive mobile data connection to browse, with limited fast internet quota. - Mozilla forgot to mention that this "RECOMMENDED" add-on wants money, and because it is "RECOMMENDED", that would "SATISFY OUT SECURITY AND PERFORMANCE STANDARDS", I didn't read the user recommendations first.
I have NOTHING against commerical software, but I want to know upfront!
There are free alternatives.

MP3 Download kostet Geld.

In full HD 1080P does not work; blocage at the end ?? My new mail is nick56@bbox.fr insteed of nick56@orange.fr

Does not let you download anything other than mp4 lowest quality... At least fucking say that you gotta make me pay to download a mp3 right on the tin rather than making me wait abit

Actually useless. The only thing you can do is 360p MP4 download. Everything else wants you to pay. You're better off using one of those sketchy Youtube to mp3/mp4 type websites

Support for Donation! Does NOT work with MP3

No descarga, solo si pagas, mala extension, no se como es recomendada.

dumpster for donations, I don't recommend it!

Nope! Youtube already lets me download up to 720 video. I wanted 1080, but when I tried to use this extension, a big error message appeared that said, "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."
