YouTab displays all your bookmarked YouTube videos in your browser. Just click on the extension icon.
You can see the title of a video by hovering over its image. Clicking on it will open the YouTube player on the same page where you can easily watch them. To return to your YouTab just click anywhere on the dark space around the player or press ESC.
If you add more YouTube videos to your bookmarks, they will automatically appear on your YouTab page the next time you open it.
You can even include some YouTube feeds in your YouTab like “Top Rated”, “Most Popular” and “Most Viewed” but also user specific feeds like your favorites and your subscriptions.
