Please can you tell me if there is a way to enter a proxy address and port to the Epiphany web browser so we can use the internet on our Raspberry Pi 2 in school.
Given Epiphany is an integral part of Gnome, it uses the Gnome-wide system preferences.
You can tell all applications on your system to use this tunnel through Gnome’s network-proxy interface. It is located under System>Preferences>Network Proxy.
The default LXDE desktop environment on Raspbian does not allow you to set a proxy server. I have created a program called pi-proxy that allows you to enter a proxy server on your Raspberry Pi. This works for most software (including Epiphany).
