Extension Metadata
About this extension
MatugenFox is a powerful extension that bridges your system colors (generated by Matugen) directly into your Firefox browsing experience.
Unlike static themes, MatugenFox uses a lightweight native messaging bridge to watch your color files and instantly inject CSS variables into every open tab. When you change your wallpaper or regenerate your colors, your browser updates immediately—no refresh required.
✨ Key Features:
Dynamic Real-Time Updates: Watch your browser transform instantly as you change your system theme.
🚀 Optimized for Performance: Built with crash-prevention logic to handle hundreds of tabs with zero lag.
🎨 Site-Specific Overrides: Apply custom CSS to any website (GitHub, YouTube, Discord, etc.) using your system variables.
🔒 Privacy Focused: No data collection, no tracking. Local theme syncing only.
⚠️ Note: This extension requires a small "Native Host" script to be installed on your system to watch for file changes. You can find the easy 1-minute setup guide and the host script on the official repository: https://github.com/Ubaidullah-Web-Dev/MatugenFox
