Download All YouTube Videos in a Playlist With BYTubeD
BYTubeD is a Firefox extension that can be used to download all or selected YouTube videos on a page in bulk. When you are on a playlist page, right click on the page and click on the BYTubeD item from the context menu. A window will appear with a list of videos that BYTubeD has found on the page. The interesting thing is, it works on any page – YouTube search results, playlists, related videos, videos embedded on a blog post, videos linked to from a blog post, and even Google or Bing search results page.
Press the CTRL key on the keyboard and select the videos you wish to download. Configure the download location, make your choice for download format (MP4 or FLV) and click on Start.
BYTubeD will then queue the videos on Firefox’s download manager. Once queuing is completed you can close BYTubeD’s widow and download the videos at your own pace.
