Using this plugin you can watch videos directly on YouTube with your friends and don't need to visit an extra site. You also have the advantage that you can synchronise livestreams and videos which have been blocked for embedded play. You also can use the features YouTube has to offer e.g. liking the current video, storing the current video in your private playlist and many more.

What changes after installation?
After you installed the plugin you will see a few more buttons on YouTube when you watch a video. These buttons can be found directly next to the like/dislike buttons below a video. With these buttons you can create a sync room, leave a sync room, or add a video to the queue.

Usage
Simply create a sync room directly on YouTube, copy the url and give it to your friends. Now you can watch the videos together.
