Zero anything. No buttons appear, no links appear, no shortcuts appear, nothing on the toolbar. It's like it was never installed. Reinstalled, nothing. Restarted Firefox numerous times, restarted entire PC twice. Nothing happens at all.

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.

Ne fonctionne pas.
Doesn't work.

lädt ewig und nichts geschieht. Video läßt sich nicht herunterladen bei mir.

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!?

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
