Power Favorites (previously XBEL Bookmark Manager), is a bookmark manager for Windows that helps you organize and synchronize your bookmarks. It takes bookmarks from Internet Explorer, Firefox or Opera, merges them into one file, builds tags, and automatically synchronizes them between computers.
Each bookmark can be personalized with notes and tags. The fast, integrated search function makes it easy to locate your bookmark. You can also view your bookmarks by tag list and tag clouds, and easily share them or mail them to your friends.
