Doesn't work well until now.

Doesn't seem to work. Just stuck saying "Generating download link, pls wait". Tried multiple times and multiple videos. Still the same. Uninstalled.

Doesn't work in waterfox, an open source fork of firefox. Like a reviewer below said: No download button appears and [when] trying to download directly from the toolbar, it just keeps saying generating link but never does

Doesn't work.

No download button appears and in trying to download directly from the toolbar it just keeps saying generating link but never does

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!
