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.

I've used this for years, and the creator is very fast when it comes to undoing YouTube's shenanigans

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

nice

Support for Donation! Does NOT work with MP3

Really easy to use and valuable addon. Well worth to spend some bucks on for the extra functionalities. My wish for the further development would be to offer also a lower mp3 bitrate for downloading just spoken conversations on YT. To save disk space

I have been using Easy YouTube Downloader Express for several years. It has proven to be a seamless way to download audio tracks I want to save for personal use. When the software hits a snag (which has been rare), Dishita, if contacted, provides direction for corrective action. His response time has always been excellent, and that has been much appreciated.

Works great, and the time there was a glitch, Dishita provided excellent customer service.

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

dumpster for donations, I don't recommend it!

Bro really put 1080p and mp3 downloads behind a paywall💀

BTW if u want to download a video and use it as mp3 file for FREE, just download the mp4 version and rename it to .mp3.

highly recommended extension, yes for full functionality you need a donation, but this is not some bad monthly subscription, these are one-time donations, so this is a great option for getting quality.
thanks to the developers
