Youtube Watch Later Cleaner

Say goodbye to long YouTube Watch Later playlists! To use this extension, go to your watch later playlist on YouTube. It will add a save and delete button to the playlist. The save button will create a CSV (Comma Separated Value) list of all the video links in your Watch Later Playlist. After all of the links are downloaded, click the delete button and Presto! Your Youtube Watch Later Playlist is all clean!
