Microsoft Edge’s new child-friendly Kids Mode designed for children between the ages of 5-8 and 9-12 that provides a safe environment for children to browse the web and consume family-friendly content. When enabled, children will be placed in a sandboxed browsing environment where they can only access Bing SafeSearch and children-friendly sites. Microsoft Edge Kids Mode is now generally available and rolling out to users in the USA over the next couple of weeks. Parents can further configure the age for the Mode and what sites children are allowed to access.
