How can I Cofigure IPFire to prevent sites on All Browsers/Devices

Hi,
I can block sites by using Web Proxy (URL Filter) on Chrome & Edge , this is working fine when user open sites using Desktops/PCs and Laptops , but it does not work when user use Firefox in PCs , Laptops also when user open blocked site(s) using mobile devices the sites open without any restriction
Please I need help in this issue

Hi,

Try to configure in Firefox proxy by hand.

Say us somethimg.

Bye.

Thank You for your reply , but this is not solving my issue because where i am working in a school and students used to bring their own device for learning through some education sites as per teachers request, so during the break or other times they can go and open TikTok or games websites as e.g. and management request to prevent that , how can I do this one each device ?

Please advice me to use an alternative settings to complete this task without touching each mobile/tablet in the school

thanks in advance and appreciate your help

Have you seen www.ipfire.org - Web Proxy Auto-Discovery Protocol (WPAD) / Proxy Auto-Config (PAC) ? Once implemented (both by DNS and DHCP), then all apps (inc Firefox) need to be set to auto-discover the proxy settings. Some apps read the system settings but other apps, like Forefox, have their own settings.

Once you have that working, you can (should) block direct outgoing access to ports 80 and 443.

There was a bit of a thread at Automatic proxy configuration using DHCP/DNS
