This has worked fine for year but no longer works at all and no updates so it is dead end extension not worth using anymore.

only can get video without sound

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
