I used to love the video download helper extension until I upgraded to Firefox 57 then needed the Video download helper 7.0 Firefox extension.

That needs the companion app which is in the DEB format for my Ubuntu software based computer (17.04 distro), it should be as simple as downloading the DEB file then clicking on it.


It should then automatically run with the Ubuntu software centre then install the app only when I click on install, nothing happens.

So,I have to run another Firefox extension because Video download helper no longer works.
