Flagium

About

Flagium — modern successor of the popular FlagFox extension for Chromium-based browsers and Firefox.

Displays the country flag of the actual server you're visiting directly in the toolbar. The extension icon dynamically changes to the flag of the website's hosting country.

Features

- 🌍 Dynamic toolbar icon with country flag
- 📍 Real server IP detection (via webRequest)
- 🏙 City, Country, Organization/ISP information
- 📋 One-click copy for IP, organization and hostname
- ⚡ Smart caching (doesn't spam APIs)
- 🔄 Manual refresh button
- 🛠 Works on Chrome, Edge, Brave, Vivaldi, Firefox and other Chromium-based browsers
- 🧩 Built with Manifest V3 (modern extension architecture, improved security and performance)

How it works

The extension captures the real IP address the browser connects to and uses reliable GeoIP services (ipinfo.io + DNS-over-HTTPS fallback) to show accurate location data.

Perfect for developers, system administrators, security researchers, and anyone who wants to know where their websites are hosted.

Privacy-friendly: No data collection. All requests go directly to public GeoIP services.
