after a long search and many uninstalls of not working yt mp3 plugins finally this one works with a referring link to a site to easliy download a track

Only redirects to a Online Downloader Website - That then doesn't download the Video, and tries to get you to install their software ... :-/

YES

I was shocked that this actually worked !!
True it opens up a window to a website that does the work, but after trying countless broken addons that do nothing, or install bitcoin miners, then I really don't mind.
I just bookmarked the website and removed this addon.

This actually works, it takes forever for the website to rehost the video, but it works. Just be patient... and make sure your add blocker isn't shutting it down (that was the problem I was having at first).

button is only half showing on the youtube page, and when you try to download a video it takes you to another page that doesn't work.

1) the download link is melded with another link.
2) I got re-directed to another page that only allowed the video to be converted to mp3.
Such a waste of time!

Tarda mucho en encontrar los enlaces. Y con frecuencia no los muestra.

Nothing works with this extension. I've been using udl helper for a couple of months now and it works best for me so far
