Making Search Engines Safe For Kids with Control D
Control D has its own Safe Search setting, found under the Profile Options section. Turning this on will force all search engines that have a Safe Search function to enable them and block any that don’t have that functionality. It’s a simple and effective way to enable these browser features and prevent your kids from easily circumventing them.
