I've been using 'Video DownloadHelper' for about a year now, and just started using this one. While the other app has not disappointed me, my initial impression is considerably more favorable.

Sometimes a video appears to be split into multiple streams/chunks, and my older app can only offer them separate from each other. However, this one appears to detect that, and offer a video to download at the top of the list that is the complete video, comprising of the in-order bytes from all streams at once.

Je l'utilise depuis pas mal d'années pour "certains sites"; c'est le meilleur vidéo downloader que je connaisse. Un seul petit reproche : pas de vidéo viewer intégré & les informations en Anglais que renvoie Ant pour paramétrer un viewer par défaut sont obscures à appliquer avec le Firefox actuel en Français (plus de nom de menu & sous menu, que de la symbolique)

Отлично работает всем советую, проблем нет пока.Все качает без проблем разработчику спасибо)

Good add-on, but have some bugs, which I reported on your site. BTW can you add option to turn off number of videos on add-on button. IMO this info is pretty annoying.
