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.

Best Downloader!

A great add-on that completely stopped working sometime this week. Then I turned of my Google account on YouTube and now it works again.

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..........

it was working great until today - then it stopped.
damn b/c i liked it so much & thought it was the best downloader. wish i knew how to fix it.

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

Probably the best yt downloader there is, but recently I started getting the error "pathname is undefined" whenever I'm signed into my yt account. Problem is, I have to be signed in in order to watch some videos...

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

It used to be a great tool, but recently it stopped working.
Error message: pathname is undefined

As of October 28, 2020, I keep getting "Path not found" message when trying to use it. Sad. It was great when it worked.

Update version didn't work. I can't download Youtube VDO right now. It show error "Batch download is interrupted". Please fix it asap.

An excellent addon, but as of Oct. 28, 2020, it stopped working. The panel that normally lists the available downloadable formats now just say "Path not found"

Worked great the first time I used it. Now I get "pathname is undefined" error.

muito bom

What a wondeful Add-on! Not working since last update (App and Firefox). Hopefully fixed soon. I miss it every day ...

used to be really good but somehow recently doesn't work at all. I did remove and reinstall and also uninstall Firefox still couldn't fix the issue.
