When downgrading to version 0.94 (the one that actually still works) remember to:
1. remove version 1.0.9 found in Firefox extensions:
type "about:addons" in the top address/search bar
2. download the old version 0.94
https://addons.vaultpit.io/en-CA/firefox/addon/youtube_downloader_webx/versions/
3. disable automatic updates

Otherwise Firefox will "upgrade" it to 1.0.9 and this extension will stop working!

The 0.94 version sorta sucks since you cannot rename the files prior to downloading, only after so you mus wait if it is a huge video file.

hi

"pathname is undefined" bug, please fix and i will update to 5 stars

не работает

Version 0.9.4 still works. https://addons.vaultpit.io/firefox/addon/youtube_downloader_webx/versions/

This was great, now it doesn't down load at all.

最近几天不能用了，不知道为什么，是被屏蔽了吗？望解决

ha dejado de funcionar despues de la ultima actualizacion de windows 10

Used to work fine, but youtube updated it's algorithms, so now it's useless

obsolète depuis deux jours

It stopped working a couple months ago. restart apps and program won't help. Did youtube block?

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.

mi sono trovata sempre benissimo, da qualche giorno non funziona mi appre il messaggio "pathname is undefined"

This add-on was absolutely fantastic, and did work exactly as advertised until the RIAA action against YouTube-DL. This is not in any way the fault of the add-on creator.

I love this add-on, used it almost every day and I am hoping a fix or workaround happens soon.

This was a great product. But like reviewer bp34 said, it is currently not working due to the RIAA's DMCA action against youtube-DL. Read https://www.xda-developers.com/youtube-dl-riaa-dmca/ for proof. Hope they get this issue resolved.
