It works on 1080p for videos that require a log in to access. Even JDownloader and yt-dl can't get videos that need a login any more. YD is working as of April 2020

ottimo per scaricare fil e video

Works as advertised. Sometimes downloads the wrong if download is requested too soon after switching to another one.

6 months ago:
[published_date] is always as "undefined" in file name.

Today: [published_date] still not working.
Also cant use '[' , '(' and other special symbols in the file name.

Excellent downloader. Only freeware is used as a companion. However, to avoid conversion errors in firefox74 on Windows 10 (64-bit), you must turn off the "Always ask for download location" switch in the extension settings form.

Praticidade facilidade e 100% de funcionalidade, esta extensão sim não apenas revolve o problema de download de conteúdo do Youtube como também te fornece várias opções do que e como fazer.
