Unfortunately old AVD version 2.4.7.50 is not supported by Firefox 57 and beyond anymore. We are continuing to return the habitual AVD look in new AVD 3.0. 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/
