My expectations were different, it actually provides the option to download but in small pcs (mb) for me it didn.t took the whole video size to download it, i even waited the total time to view online the video, but in the clicking option of this add-on it wasn't but just few mbs of the whole video, so i unistalled :(

Don;t download videos.

"Professional" só no nome! O complemento tem publicidade e não baixa vídeos do YouTube.

Absolutly uncomfortable interface

doesnt work

Findet keine YT-Videos...

Bait and Switch
I have never reviewed a Add-On before. I have enjoyed a lot of great ones, suffered some lame ones but this is a bait and switch scam and I am frankly shocked that Mozilla would permit it on their site. Nowhere in the description does it warn that:
A. It requires you to install a downloaded .EXE, from somewhere other than Mozilla, that gets flagged by Microsoft Defender as: “This program has potentially unwanted behavior.”
B. It puts a big QR code watermark on your video unless you pay $28 for the licensed version.
If you read the other one star reviews you will get the same story, the truth. It does work, albeit slowly, and does have memory leaks.
They even got tossed off PayPal so you have to use your credit card. Nah.

Doesn't work, at all.

Pas de version originale ou bien pas de son du tout. Aucun intérêt. Download helper était très efficace, ce n'est plus le cas. A désinstaller sans regret.

En muchos sitios NO funciona.

Darmowa wersja nawet z YT nie pobiera, od razu proponuje wersję płatną, szkoda czasu na instalację.

"No videos found" Wasted 2 minutes of my life.

not working
