Detects the videos but companion app doesn't work. Awful UI.

It is the strongest Add-on video download, without a doubt, it can be used in 99% of the reproduced videos, despite its effectiveness, sometimes the external tool uses many resources and can give a low performance to the PC while downloading, But that does not affect the general performance of the app, the only ruling that I have personally had so far, is on YouTube, unusually slow discharge and when it is never becoming 0%, outside of that recommends.

using this add-on has been mostly simple. it was annoying at first but i got it figured,well mostly

サクサク動きます、気に入って使ってます

Ich bin mit den Downloads meist zufrieden. Manchmal ruckeln sie (es fehlen anscheinend einzelne Bilder).

Honestly, despite it's oft documented shortcomings (odd video formats, glitches when Mozilla endlessly 'touches things' no-one asked them to touch), VDH is a remarkably consistent little tool. Good job guys!

Merci VDH,facile à employer et très efficace.
