之前一直很好用，现在有几天失效了，希望可以早日修复，感谢。

It's not working :(

The best Youtube utility for this purpose, which normally works flawlessly. As of 25th June 2021, it's stopped working. Not sure whether this is because of the recent Firefox update (unlikely) or more fun-and-games from Youtube. Whichever, I miss it and would like it back working asap.

28/6/2021 Update

That's a rapid fix. Thanks to the developer for getting it going so quick.

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

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!
