doesnt show up on the top right corner, and not elsewhere either.

easy to download the mp3

The button literally does nothing. I suspect this addon is a scam to scrape personal data.

Не скачивайте, по ссылке переносит вас на вирусные и машеннические сайты. Скачивание не работает.

It's literally a broken add-on, DO NOT DOWNLOAD IT, report it

Wo ist der Download-Button oder Infos zu alternativen Möglichkeiten, Videos herunterzuladen?

This brought to pornografic contents and never downloaded the content as expected. Very bad

Simply malware. If you ever can get a video from it, it will be 360p poor quality.

Simple and without the need to give risky permissions. All those extensions requiring to get all your data just to download an mp3 are suspicious to say the least. I found this solution simple, of course the ads are annoying, but worth the service.

Quality of downloaded video is bad. Speed is terrible. Internet page of purported author is dubious at best.
