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 :)

This awesome extension is regularly broken by either Firefox updates or YouTube back-end changes. Kudos to the dev that maintains it!

Stop being surprised when it breaks - and remember - people respond quicker and are more likely to fix something if you ask nicely, especially when they do it for free.

YouTube doesn't really support this extension existing, because they want to charge you money to "download" videos, but only to select devices in a very limited fashion, inconveniently. So YouTube either makes changes without regard to breaking this, or intentionally break it. And Firefox updates only seem to ever make things worse, not better, so yeah.

[older issue that probably still has something to do with youtube breaking it regularly]
Apparently 10-23-2020, the RIAA filed a DMCA takedown against the code repositories, used by extensions like this, to download YT videos. Cause "piracy".

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

It doesn't work, infoplayer 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

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...

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"
