• On the page in the browser (I use Firefox), open the Network Activity monitor as the video is playing. (Ctrl+Shift+E)
• type mpd and find playlist.mpd (or any other octet stream)
• find the https:// adress and the filename in the GET and header information in the network analysis window.
• Use youtube-dl (command prompt tool). If you don’t like command line software then get a GUI like youtube-dl-gui. Or from the command prompt just type youtube-dl.exe https://www.youtube.com/watch?v=…..number from adress bar … and it will download your youtube video.
