## Description

"IPvFoo" is a unique Firefox extension designed to raise awareness about the global IPv4 to IPv6 transition by displaying server IP address in real time. It also provides an overview of IPv4, IPv6, and HTTPS information for all page elements. Respectful of user privacy, IPvFoo keeps data in RAM and operates in read-only mode on the network. The add-on features a red 4 or green 6 icon to differentiate between the IPv4 and IPv6 fetched pages. Additional features include a detailed table for each domain, WebSocket handshake and Service Worker data fetching indicators, and a right-click option for address lookup.
