Power Favorites (formerly 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, and automatically synchronizes them between computers. You can use it to detect dead links and duplicates if you have many bookmarks.
Each bookmark can be personalized with notes and tags. The fast, integrated search function makes it easy to locate your bookmark. The hot list and recent list folder allow you visit the bookmark you frequently visit quickly. You can also view your bookmarks by tag list and tag clouds, and easily share them or mail them to your friends.
