Really sad to see the old version gone. This one is idiotic to say the least...... PITA to use. Last version was so well done. Simple and easy to use. Can't understand why the change.
It was the best the way it was. Just needed to update if for FF v57.
Unfortunately old AVD version is not supported by Firefox 57 and beyond anymore. You still can install old AVD version in Firefox 56 and below here: https://addons.mozilla.org/en-US/firefox/addon/video-downloader-player/versions/
