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.

I have been using this add-on for some time. Worked great.
Then I encountered:
cannot detect url_encoded_fmt_stream_map or adaptive_fmts
Tried to search for solution. Couldcn't find any.
Tried to reinstal the add-on.
That solved the problem :)

The best add-on to download from youtube. Thank you.

The downloader is fine. I want to know why the god damned preferences page opens every time I download something!

Used to be the best video downloader add-on. Now all I get is "cannot detect url_encoded_fmt_stream_map or adaptive_fmts" instead of a download list.

No sound after downloading 420p video.

One button click to quickly download a video. Worked totally as expected.

Quick download option downloads only a low-res video even if you are watching the HD version playing in your browser. Does not display high bitrate download options for videos. Audio is downloaded separate from videos.
