DO NOT UPDATE. Awful May 22nd 2024 Update. Used it for almost a year now. Used to be 5 star extension/app. New updated interface takes 7 seconds to load, versus the 1 second before. Larger videos which require the companion app now have about 1/4 the screen covered by a QR code. Unusable for out-of-browser videos, 7 times slower for browser downloads.

It doesn't work as expected

Although video download helper sometimes reports that there is no video content when a video is running, once the download assistant app is installed it doesn't do that as much and you can capture video from many sources, besides YouTube.

Personally I recommend Video DownloadHelper added to Firefox, and granted all permissions, it works really well and NO TRACKING allowed.
