CoordCloak per qtChi

CoordCloak is a Firefox extension that overrides your browser's geolocation with any coordinates you choose. Enter them manually, paste a DMS string and watch it auto-convert, or pick from a preset city. Flip a toggle and any site asking "where are you?" gets your answer — not the real one.

No data collected. No accounts. No internet required. Fully open source.

🚀 How It Works

At page load, CoordCloak injects a small script that replaces the browser's built-in navigator.geolocation object with a fake one that returns your chosen coordinates. Any site calling getCurrentPosition() or watchPosition() gets your fake location instead.

Note: This only overrides the JavaScript Geolocation API. It does not mask your IP address. For full anonymity, pair with a VPN.

🎯 Features

• 🌍 Spoof to any coordinate on earth
• 📐 DMS auto-converter — paste and go
• 🏙️ 8 city presets for quick switching
• 💾 Settings saved between browser sessions
• 📡 Broadcasts to all open tabs at once
• 🔒 Zero data collection — everything stays local

📖 How to Use

1. Click the CoordCloak icon in your Firefox toolbar
2. Enter your coordinates one of three ways:
3. Paste a DMS string like 40°34'27.07"N 105°04'57.99"W — it converts automatically
4. Type decimal lat/lng directly into the coordinate fields
5. Click a city preset — New York, London, Tokyo, and more
6. Click Apply Fake Location
7. Reload the tab — that site now sees your fake position

To turn it off, flip the toggle and reload.
