Sorry didn't work at all. Download button occasionally shows up after a couple refreshes but its always greyed out and the toolbar button just processes forever. Went through the support steps which mentioned opening in incognito but same problem.

it doesn't work at all

Maybe it worked in the past, but it doesn't anymore.

There is no "button" or way to start download!?

The button to select what to download doesn't appear, and when I open the add-on directly from the Firefox toolbar, it stays thinking and trying to generate a download link but doesn't do anything.

It does not work.

Ya son varios meses que no funciona, espere a que se solucionara pero no fue así.

Non funziona, non appare nessun bottone per il download

I remember using this a couple years ago and it was great. Doesn't seem to work anymore unfortunately. Doesn't even show the buttons bellow the video as shown in the screenshots (examples).
If this is the #1 downloader for youtube then downloading from youtube is f***ed.

Does not appear to function in any way. Just stalls at the Generating URL pop up.

Try many times for last few months and still dont work: Generating loading link infinite... but nothing happens...

It just doesn't work! Nothing happens after you install it!

Does NOT WORK! (+ $$$) This YT-download EXTENSION requires it's - "own server for processing", which REQUIRES a PAID upgrade account. = PAY $$$ TO PLAY !

FINGER WEG!! Hat früher mal funktioniert und war eigentlich Top.. Irgendwann ging es nicht mehr und man müsste angeblich Premium machen um, was weiß ich. Da ich immer zufrieden war hab ich für Premium bezahlt.. Hat nichts geändert. Er läd nix mehr runter, es wird nicht mal mehr etwas zum Download angezeigt, außer der grüne Button.. Was etwas frech ist, das man weiter für Premium wirbt - ALSO FINGER WEG, KEIN PREMIUM !!!

simplemente no genera los links de descarga

it does not work

Did not work.

I just think it's inappropriate that since their app doesn't work and I was requesting a refund that the captcha, was too small to show all the characters, and had funny colors to it, so you couldn't figure out what it was. I've since uninstalled the extension and I'm not interested in a magical fix just like a refund. Again thank you have a great day.

Simply doesn't work. Since all of the screenshots look like they were taken in the 17th century, I imagine that's also when this extension was last updated. The fact that you are still charging people for licenses for this is unbelievable.

Completely useless! I tried to download a 10 minute video, video ended and the app had still not generated a download link
