Used YouPlayer for Windows?
Editors’ Review
YouPlayer lets you create playlists of your favorite YouTube videos to watch while you're browsing the Web. While its missing a minor convenience, its definitely a keeper.
The program operates as a sidebar in your Firefox window. There are two view panels--one for viewing the video and one for creating playlists. A hot-key combo lets you activate or hide the sidebar, and you can opt to play videos in a separate tab. We loved the drag-and-drop feature, which made it easy to quickly add URLs to our playlists. Once you drag it, a right-click will let you edit the entry so that you can assign it a name. There's a save feature to save your playlists to your hard drive if you want. It would have been nice if you had the option of playing the videos continuously. When one video ends, you have to click the next item on the playlist. But that's about our only complaint.
Users of all skill levels will find this free program a great tool for watching their favorite videos.
