Fantastic addons, work flawlessy even on some weirdly implemented website, as long the video player is well know.
The only thing i hate about this addons is the fact that i i choose a location for the file, and a name, the name i choose will not be displayed over the progress bar (at least until the download reach 100%)

My favourite Firefox addon makes downloading videos in 360p, 720p & 1080p so easy!

On some sites, when it detects a lot of videos (most of them advertisment) it's difficult to distinct the main one.

Presque parfait, ne fonctionne pas avec toutes les vidéos, je dois le coupler avec turbo download manager pour combler ce manque. J'aime vidéo downloadhelper et je le recommande

merci pour le partage rapide des séquences video

とても簡単　使いやすいです。

Been using for years great app good for mp3's too.

installation gratuite inexistante !!! c'est une escroquerie!

On some websites, it does not search for *.mp3 audio tracks and only offers *.mp4 videos.
