After trying to find a YouTube downloader that would actually complete it's given task of converting a single rare piece of music into an mp3, I tried this by uepselon.

Success finally, after at least a dozen failed add ons, and a donation to them on it's way.

Thank you so very much.

thankU 谢谢

es perfecta.
pero como todo,se podria mejorar.

ok mantap

Works, it automatically brings you to a third party website and begins the download coconvert.com. Not exactly what I want but it does work, many others here do a similar thing but this one automatically starts the download at least while other applications are just shortcuts. Less messy than similarly functioning plugins.

If it didn't redirect and just showed up in the download folder then you'd be perfect.

nginx "404 not found" error every time, even with version 2.4.1.

404 Not Found error, no matter what Youtube video you'd like to download as MP3.
EDIT: yes, with 2.4.1 it works, thanks

good

YouTube Download Plus was just one of several dozen Firefox extensions claiming to be the best video downloading tool available in the 21st century. Frankly, I thought I'd try it because I was looking for something simple and that worked as advertised, two small criteria that, sad as it sounds, most of the other extensions I had tried failed to satisfy. But this extension satisfies BOTH of them: it's simple to use, doesn't take up much space and does exactly what it claims to do: "Download YouTube videos as MP3 or MP4." This may sound like a simple request, but it's not. Or at least it WAS not. Thanks to uepselon, it actually HAS become so, and you have my gratitude. :)

Doesn't work, don't create an app that calls itself a download app when you send the user to a page that tells them to set up their own downloader service to download, lol, its like whats the point of your app just to trick people or make them do all the work. Definitely try another youtube download extension before this one.
