updated for beta testing, a new version
vers.0.6.0 --- it works well and hope it has a long future... appimage application bundle currently
...as a user it is currently a stand alone app to the desktop (Linux) 64 bit
testing for the future.
it works - deserves support.

When well integrated into the Firefox browser it is the best I have ever used...
No other down-loader of videos on YouTube come close to the quality or flexibility of this add-on application - I am using Linux in a 64bit environment. this works.
