I find it extremely unfair when some people rate this excellent extension so badly, it doesn't deserve it. The cause of the malfunction lies with Youtube, who are constantly changing their software in such a way that extensions like this one do not work. Therefore 1-star reviewers: Think about that and be a little ashamed!

dont work

Thanks for the fix :)

Constant error: info.player_response is undefined

something wrong. it doesn't work.

----------June.29.2021------------
completely fixed up! thanks a lot.

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

It stops working a few days ago "info_player.response is undefine"

best

não funciona mais.

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

Great tool but currently not working. Fix pls

Fine tool but it has just stopped working. When I click on quick download nothing happens. This, after months of use.

info.player_response is undefined!!!!!!
Pleeease fix it!

I'm still leaving 5 stars as it has worked flawlessly for ages but needs an update as youtube has changed something and now there is an error "info.player_response is undefined". Hope the dev gets it up to par fast!

the extension was great, but it stopped working... then it was great again, but then it stopped working again. youtube is trying hard to stay ahead of the game.

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"

Overall it works best from all other addons, which are supposed to be able to do the same. This one is slow but reliable and doesn't merge Video and Audio in all cases. But this can be done by hand.
