ViewTube is a useful Chrome extension for watching YouTube videos on Facebook, Twitter and Google+. It opens the video clip in a movable window rather than opening it in a new tab or embedded in the page. Besides, it includes a full description of the video, comments and related videos. You can like (or dislike) videos directly to YouTube and even post comments, without having to click over to YouTube. Interested users can install ViewTube from Chrome Web Store here (no configurations are required) and enjoy watching video on Facebook, Twitter or Google+ in regular, large or full screen mode in a movable window.
