A new, faster version of the KidZui Add-on is available: KidZui K2 Add-on
Protect your kids online and expand their online experience with KidZui, the Internet for Kids. KidZui is a Firefox add-on that with one click turns Firefox into a kid-safe environment with over a million kid-friendly websites, games, pictures, and YouTube videos. KidZui is a free Web browser, search engine and online playground for kids 3-12. Parents and teachers review content for KidZui so your kids can surf independently. Kids build avatars (called Zuis) to express themselves online. They earn points for exploration and discovery. They can tag content and share it with parent-approved friends. When locked down, KidZui prevents kids from closing the browser, downloading files, or opening other applications. This is a great way to let your kids independently explore on Firefox without worrying about them using the adult Internet, or accidentally deleting important files.
