Changed my rating after years of successful use. The October 2024 change at YouTube made this extension ineffective for me, and nothing new since then here so I bumped down to three stars. I don't know if upgrading to the PRO version will get things back to working, but I am not chancing it since I don't see any updated announcement in support page since October. I am using "YouTube Downloader (UDL Helper)" now to download 360p video from YouTube if anyone is desperate for an alternative to this
