Great extension, but don't know why, downloaded video watching on TV, audio and picture is OUTER-SYNC, ONLY video format 1920 X 1080 is exempted; But this issue didn't happen on youtube.

Very GOOD Availability～
可用性極佳👍👍
歷經 Firefox 多次的更新改版，一直都能保持可以使用👍
相較其他類似的附加元件，往往在 Firefox 一改版就失效 disable ，而且遲遲未能修復。

À fonctionner là où "Video DownloadHelper" ne trouve pas de vidéos ou n'arrive pas à finaliser l'assemblage vidéo.
Pas parfait, il affiche tous les morceaux de flux vidéos mais il y a un symbole violet pour repérer la vidéo complète avec la résolution préciser sous le titre. Il faut installer le fichier AVD-NativeApp pour que ça fonctionne, fournit via l'application

Testei em 2 vídeos, não funciona, uma porcaria, peço que parem de encher o pc dos outros com lixo.

Currently it has issue with forming correct output file for sites for me. I have submitted the issue with screens and output file comparison on the support link. I hope you fix it soon.

Best Video down loader Firefox extension found on options. Not offered for other browsers. Would like to use it across all browsers.

very good

It is 2020.
So many bad things happened.
Bad news, bad dream, bad reality, bad add-ons.
Firefox still exists, so I still am for it.
However, add-ons which were good & free, were no longer the way they were. I did try relentlessly to find the "downloader" add-on that works with no gimmick day after day. Until 7 days had gone by.
The search turned up for there were only 7 of the Abrahim, ahem, I meant, add-ons of its kind that shown up as result.
However, I tried to use them each, but none did work.... of course, even if you use 7 altogether, they still no miracle. All of them now only works for the sake of worldly gain, for there were no miracle left in the hand of holy land.
Then, I found the "Ant".
It works. End of story. Fin.
