It does not work to download mp3 even with PRO version. The external application does not work neither.

Works pretty much all the time. Word to your momma.

no mp3

It's slow but works completely.

It works but my only issue is that there is nothing to indicate that it is downloading.
At least on my end. So I press the "button" and eventually it shows it downloaded.

This is one of those extensions you forget you ever installed, just up to the moment when you need it. Sure, downloading videos is a game of cat and mouse, so it might not work every time, but most of the time it really works—and the author has been maintaining this extension for years on end in their own free time.

it works 👍

It worked perfectly the first time I tried it, then it affected everything I did in Firefox and the whole browser experience changed. Even when I uninstalled it, this extension was still somehow sending notifications. I'd recommend avoiding it.

It works again! That's great. My only issue is that there is nothing to indicate that it is downloading. At least on my end. So I press the "button" and eventually it shows it downloaded.

funciona muy bien pero debes abrir y cerrar l pestaña porque de lo contrario descarga el mismo video varias veces

I'm impressed! It works differently than it used to, but the YouTube obstacles have been clearly hurdled and this new version works like a charm with video up to 1080p. Couldn't be happier.
