I paid for this add-on but now they want $39 a year to use their desktop version instead because "YouTube is blocking" them. There are better options out there that work and are free.

Doesn't work. Utter crap. It generates the link endlessly and u need to upgrade to do anythyning. so, its a scam

Sorry, it's become a scam that only can download popular videos through the cache of other paying customers in the last 24h. What a joke!

Got scammed. Donated to get "immediate access to high-quality downloads without waiting for the next version". Go to download and get the message "Youtube has blocked our proxies once again, I am working on a fix, pls. try again after sometime" Total scam.

Scammed again, worked for about 2 weeks the downloads 0kb files. I wish Mozilla would ban this useless scamware.

I paid for the upgrade, now it shows that I didn't.

Dead as disco. After recent update of Youtube code even the button has disappeared.

No funciona, o se queda generando el link o te da error para descargar en videos de youtube

Ha dejado de funcionar desde las últimas actualizaciones. Indica descarga fallida.
Habrá que buscar alternativas.

I echo what Firefox user 18352310 says and ask: does anyone know of a utube downloader that works correctly?

Firefox user 18352310 "Youtube only allows download of 360p vids with this app now. Some videos not at all anymore. Needs update to keep up with youtube blocking downloaders."

It no longer works.

It's a FAKESPOT ,, Steals your Money with Donation Requests & Never changes. Compare download Code sigs between updates .. De Nada !!

This used to work, now the person maintaining this addon is just scamming money in the form of a donation!!

Without question this has got to be one of the most USELESS extensions EVER!! Click on it a you get a waiting to create link and the thing just goes on and on and on and nothing happens. Don't waste your time on this. At one time it was awesome, now.... IT'S CRAP!

This guy's a Scammer, extorting us all....even after paying $ it's now stopped working (and he won't fix it) and he's demanding $30 a year...EXTORTION!!!!!

This add-on works only for a short time and even then only at the 360 resolution. Then it stops working, it says the size of the 360 file is zero. The downloads history just says it failed. If course if you try any other resolution it gives some flannel that YT changed something and so they need you to pay for the PRO version. I have seen this tactic on some VPN add-ons.

So it works fine for a short period or a few downloads at 360, then it stops and your only option is to pay them money. This is the message if you choose any other resolution or format

"Youtube switched to separate audio/video streaming technology for higher quality formats and no longer provides direct 720p (Since 24 September 2018)/1080p/mp3 streams. Converting these streams to downloadable formats for you needs powerful server infrastructure, therefore 1080p/mp3 downloading has been limited to PRO users."

doesn't work at all.

Was the best - Now it's dead. Youtube AI is seeing red. Use to be fixed within a week, month gone but still deader than dead.
