They don't tell you that it doesn't work anymore for youtube until after you buy it. Neither low quality nor high quality.

Used to work doesn't anymore - is there something that works in Mozilla?

Garbage, only allows 360p mp4 to be downloaded for free users and even that fails and doesn't download.

Hasn't been working for quite a while now.

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!!!!!
