Although Firefox doesn't have a website blocking function, you can install extensions to detect and block websites with restricted and adult content. If you need a more comprehensive approach, you can edit your server file to block websites across multiple browsers. If you need to block on multiple devices on the network, using a service like OpenDNS is the most effective way.
