The add-on is supposed to download videos on the internet for you. However it edits and modifies those videos during the download process to include a QR code advertisement that takes up to 1/4 of the available video space. This QR code advertisement links back to the add-on's webpage. This advertisement is not listed or mentioned in the add-on's description prior to downloading. This is a relatively NEW addition to the add-on within the last year.
UPDATE: now the app doesn't work on Youtube, utterly useless.

Am I missing something? this extension will not work. Looks nice on the toolbar though

Now they force you to buy or you get a BIG QR-Code on your videos!!! Trash-Addon!

1/3 vom Bild des Videos wird vom Wasserzeichen verdeckt. Nein danke.

It adds a QR code the videos. So it is an useless add.

Si quieres usarlo hay que pagar y si no te plantan un QR que te tapa un montón de pantalla.

Desinstalado.

Ekranın yarısı satın alma sayfasına giden karekodla doldurulmuş. Herkes kaldırsın. Bi anda paraya gözü diktiler

I'm not gonna pay for something I used for free a few months ago

useless

po aktualizacji trzeba wykupić licencję ponieważ bez niej na ściągniętym wideo jest kod QR. Darmowa wersja jest bezwartościowa także nie polecam

Havia dado 5 estrelas recentemente, mas infelizmente o add-on começou a exigir uma 'contribuição' de $28,95, o que é extremamente caro pra essa aplicação. Colocaram um QR Code imenso nos vídeos, forçando sua compra. Foi bom enquanto durou, mas agora infelizmente não é viável seu uso

Used to be a great extension, but now it sabotages everything you download with a huge QR code - something I would think is a infringement of the original creators copyright.

Impossible de télécharger vidéo ou réel sur Facebook... "Ce média n'a malheureusement pas pu être téléchargé" :(

needs to install adware

used to be good, now terrible

Не работает! просит загрузить еще какую-то стороннюю прогу. Возможно, вирусняк.

addon was great for a time. now adds a crappy qr code watermark to the video. worthless. stop being a shekel sniffer.

Another decent resource ruined by the greed of the developer. Do not bother; every video download comes with an annoying QR code that can only be removed by payment.

it was amazing until the "watermark" aka the giant qr code making the video unusable
