I recently reviewed this to say it was no longer working.
I downloaded and installed version 4.8.6.
the problem has been resolved and Video DownloadHelper works fine.
Thank you for the quick fix.

it has stopped working.
youtube must've changed some coding.
it worked fine up until today.
this extension is 5 star.
