Sketchy as hell.
Too many permissions, requires a third party companion app to be installed, which they have to specify that it is definitely safe (with a smiley...). Loves to add watermarks to your downloaded videos to pressure you into paying for a license, even though most of the tools their use are third party open source programs they have nothing to do with.

Requires a license to get rid of the watermark.

Used to be free, they have added a massive QR code blocking a third of the screen unless you pay for their license.

It's not free at all.

The new update only downloads the entire video half the time. Otherwise it downloads 9 or 21 seconds.

When I start Firefox the three balls are coloured but as soon as I go to Youtube the turn grey and even the sidebar doesn't work.

Ce module est de moins en moins gratuit puisqu'il ajoute un QR code aux vidéo et que les fichiers audios sont de moins en moins pris en charge dans la version dite gratuite ! l'incitation vers la version payante est de plus en plus lourde ! Dommage !

Worthless c*nt developer now charging for this add-on otherwise a huge QR code? Is this some kind of a joke? Remove this trash from firefox add-ons. Developer has lost his mind.

Suddenly now it costs 28$ to save download a video. Otherwise they slap a massive QR code on your vid that covers like 30-40% of it.

Suddenly changed to $28.50 for a license which is ridiculous, particularly for those of us who have donated before.

App companion? not great, but OK.

Not 1080p downloads? OK, I can live with 720p.

MASSIVE QR code covering almost half of the screen? Nope

I've been using this extension for years on different browsers, and I don't mind if I have to pay for something useful as this was, but this is not the way to ask me to do it. Sorry

18 dollars for an add on?? You gotta be kidding me. It may not be much in US but basically everywhere else is absurd.

Speichert nicht mehr automatisch die Audiodatei mit. Nicht mehr hilfreich. Schade ... Alternative???

USELESS!! Free version downloads with a GIANT QR Code that covers 2/4 of the video. What's the point?
