🛡️ Young Domain Guard

A browser extension that alerts you when visiting websites with recently registered domain names.

🤔 Why?

Phishing and scam domains are created and abandoned constantly — most live less than a month before being taken down and replaced. Traditional blacklists can't keep up because new malicious domains appear faster than they can be catalogued.

Young Domain Guard takes a different approach: instead of maintaining an ever-outdated blocklist, it checks the age of the domain you're visiting. If the domain was registered recently (default: less than 30 days), you get a warning. Simple, effective, and always up to date.

⚙️ How It Works

1. 🌐 You visit a website
2. 🔍 The extension queries RDAP (Registration Data Access Protocol) for the domain's registration date
3. 🚨 If the domain is younger than your configured threshold, a warning banner appears on the page and the extension icon turns red
4. ✅ Older domains show a green "safe" indicator

Results are cached for 4 hours to avoid repeated lookups. Major well-known domains (Google, GitHub, Amazon, etc.) are automatically skipped.

✨ Features

• 🧩 Works on Chrome, Brave, and Firefox
