Version 1.1.2 doesn't work for me on any video, with or without music. Displays "Unable to retrieve video metadata." Version 0.9.4 also doesn't work for me.
Having trouble with another Firefox extension named VideoDownloadHelper also.
Both of these quit working last week after installing the latest Windows10 updates.

Bug: pathname is undefined
Please fix this ASAP!!!

currently addon is not working; getting error info.player_response in undefined.
I use a different downloader getting problems simulateously. It explains: "YouTube removed the alternate method of getting track information" and they offered an update for making their tool working again. Now I'm waiting for an update having this nice converter working again.

Today (06/30/21) i found addon version 1.1.6. Together with firefox version 89.0.2 bug is fixed and it works properly again; thx.

(06/24/2024) I used the download addon from feller a lot and it works fine up to two days ago. Now it is telling „Batch downloading is interrupted“ each time I try. Meantime I have updated Windows (11 23H2), Firefox (127.0) and yD addon (1.2.1) to the latest versions, but error message still occurs. Seems like I’m not the only one having this issue

(01/23/2025) Addon YouTube Video and Audio Downloader (WebEx) is still not working. I do not recommed using this addon and changed my rating.

Worked before, but now getting an error message that reads "pathname is undefined" with no way to fix. Developers . . . please fix. This is a fine product.

Worked well until today. Now receive "Batch downloading is interrupted" message, and nothing will download.

I don't know if it's a glitch or like a bug with this, but IT DOESN'T DOWNLOAD. I've been trying hours trying to remove this and install it again to download the music. It doesn't work. Please fix this asap..........

Funcionaba muy bien hasta que ya no pudo mas. no hace nada, se queda pasmado

fake, does not work, error message pops up: can't access property startswith...can't believe that nonworking extension is listed as recommended

-------

A new message appears since the update of this module : Unable to retrieve video metadata. Please can you find a fix.
