Fox Web Security is designed to protect you and your children against the dangers of the Internet!
This add-on automatically blocks known dangerous websites.
It also can block unwanted content that is not suitable for children.
In contrast to the existing add-ons - Fox Web Security is very small and run like the wind.
But a high speed and small size do not mean that it will perform a bad job!
Thanks to professionals in the anti-virus domain and the innovative algorithms of this add-on, Fox Web Security provides high-level protection.
This add-on provides protection from web threats and restricts access to adult content on the basis of information from well-known, safe and free DNS servers:
- Yandex.DNS: https://dns.yandex.com/ (Security + Family)
- OpenDNS : https://www.opendns.com/ (Family Shield)
- Norton ConnectSafe : https://dns.norton.com/ (Security + Pornography + Other)
