This is downloader is terrible. All of a sudden I am not able to download you tube videos at all and it is affecting two websites I manage I get this message. "Your browser does not currently recognize any video formats available." The help page has no solution. My two websites have the same message for previously working videos. Everything works on Microsoft Edge and Chrome. What gives. I use Firefox Quantum 58.0.2 and I like Firefox but I am about to switch to a working browser if a cannot download videos. dsburgess@durango.net
