Appears to be broken; it acts like it downloads the files but then immediately deletes them, regardless of what kind of download is being done (audio-only/video-only/both).

This started about a month ago (June 2021) and has yet to be fixed. Before June or so it was working fine and would download audio/video/both. So either Youtube changed something or the code broke, either of which have rendered this inoperable.

Constant error: info.player_response is undefined

Do not work... Only an orange box saying "info.player_response is undefined"

It's not working :(

Stopped working recently even after reinstalling, "error: info.player_response is undefined"

dont work

Constant error: info.player_response is undefined

It used to work very well, now it just says info.player_response is undefined

it says info.player_response is undefined

Even if I roll back Firefox to an older version, it was shown "info_player.response is undefine" and not working

não funciona mais.

It doesn't work, doesn't show on teh toolbar.

O tamanho do painel não está compatível com a versão 89.0.1 do Firefox. O item "Download Painel" retorna "info.player_response is undefined". Por fim, o complemento não é completo em si, o item "Conversion Tool" requer o complemento "Media Converter and Muxer - Audio Tools por InBasic"

extremely slow!!

It is a very strange UI/UX, mostly for converting into MP3, not for video

It's a joke. Doesn't work.!!!!!!!!!!!!!!!!!!!!!!!!!
