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.

used to work, but not anymore

It's not 31mb for a single song

Nice Danke

It does not work.

Anyway I would never install it in my main browser, because its code is secret and it can see all my passwords and other things that I write.

See:

https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions#w_access-your-data-for-all-websites

"The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords."

Doesn't seem to work, all it does is load on the download page, and it shouldn't need to take 20 mins to nab a song.

This extension will place a donate button on every YouTube page that just says "Donate". The donate button leads to an obscure patreon page. I thought my computer was infected with malware.

Não informa a qualidade de mp3 e nem a resolução de vídeo
