I've been using this quite for a while and i find it awesome!

Pas de blabla, télécharge des vidéos correctement et sans efforts.
No bullshit! Downloads videos well and effortlessly.

Amazing

Nice tool, I like it to have it on the left side of my browser. Shows what I hear and give the possibility to download it with good quality. Cool

Very useful, works fine when others failed

Very useful addon that allows to extract otherwise unobtainable content.

Seems to just simply work, straightforward, great for personal offline viewing (saves on data)

Video DownloadHelper Integrates into FireFox Menu Bar very well. After many months of use I find its operations dependable. The menus are easy to understand.

Good

Sehr hilfreiches Tool, falls man sich ein Video in Ruhe noch einmal ansehen möchte.
Für mich hat sich die Bezahlvariante ohne Wasserzeichen sehr gelohnt.
Das Produkt entwickelt sich immer weiter und wird gepflegt.
Macht weiter so :-)

Excellent add-on and very useful

Fantastic tool, I am using it for long time, very intuitive and useful.

super!!!!!!!!!!

Got QR code in corner.

Watermark takes up more than a quarter of my screen covers up the subtitles in the video. Completely worthless.

good！
