Everyone:

Firefox crippled most of its extensions beginning with Version 57. (Why they borrowed technology from Google, I'll never know.) The developers of the Video Download Helper responded by creating a Companion Application.

I have tried installing that application dozens of times. But Firefox refuses to recognize it. And without that recognition, VDH will not download most videos from YouTube. (Was that the idea?)

Has anyone gotten that companion app to work? If so, how may I do it?
