As of June 26th, 2021 it has been a week or more that YT has changed its format to separate Audio and Video to improve quakity and playback.

I have been using this little tool for a few years and guessed it pulled files from our cache. It has worked perfectly until YT changes up things. Then a short time later the extension is updated and works again.

IMHO this is one of the very best tools for YT.

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.
