I am trying to download this video with downloadhelper, the firefox extension
but I just get audio only.
This is particularly with this video clip.
The solution must use Downloadhelper, the firefox extension.
The solution must be tested to successfully download that video not just the audio of it!
If you do succeed, then the question is, why am I not succeeding in it?
This answer is not a duplicate of something already answered, since i'm asking specifically for regarding downloadhelper firefox extension, and a mysterious problem of audio only, specific to this clip.
Added- It seems the downloaded file does include Video(even though the 10min clip is only 20MB). It wasn't playing before, but it is now. I haven't re-downloaded it. Before it was just playing audio and displaying a blue screen with no text when I played it in VLC.
