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.

It's not 31mb for a single song

It does not work.

"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."

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.

Trash, is a front for a separate converter that throttles down to uselessness after 3 conversions.

Used to be good. Not anymore
