My most favourite add-on is going down down down, what happened? Oh no why this is happening to me? Please bring the old addon back in the new version of firefox........otherwise there is no use to it.
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/
