Ignore the naysayers, easily the best, most comprehensive free plugin for this use available. YouTube made some backend changes, which disabled it for several days and the developer very quickly responded to update and get it back in perfect working order. Hope those quick to pronounce it 'broken' and point the finger don't discourage the dev as they're doing a tremendous job - Thank you!

Thank you for fixing it so quickly.

This extension is really the best there is. At the moment it does not work because YouTube has made some changes to its code. But I'm sure it will work again soon.

Yes work again after update today 28 June. But sometime it may not work, just try again. Tq

Error msg:
Constant error: info.player_response is undefined

Fix ok, thanks.

Constant error: info.player_response is undefined

Great Addon! Have been using it for years.
Although some times it does not work as expected it is still a great ext.
I hope feller finds a fix for the new update soon. Can't wait to use it.

I LOOOVE it,it worked verry well,easy and quick! But 1 week ago it stopped working and i have really no clue why. Reinstalled everything,also native message host,browser restart,ect...nothing helped so far. I think YT has modded there website again,and thats why this REALLY Fantastic extension stopped working. Cant wait to see it working again ;)

Do not work... Only an orange box saying "info.player_response is undefined"

--- edit --- great job fixing it. thanks again feller for this wonderful plugin and the time you put in to it. ignore these 1 star disrespectful fools


Listen you morons: this guy feller has made a great add-on which is free to use and when youtube changes the functionality of their site then it causes issues for the plugin but feller is always on the case diagnosing the issue and then writing a new bit of updated code to get the plugin functional again. You idiots that give a 1 star review and cry because it stopped working really p*ss me off. Youre all a bunch of fools that have no understanding of programming and shouldnt leave bad reviews. IDIOTS !

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
