About this extension
Phishing and scam domains are created and abandoned constantly — most live less than a month. Traditional blacklists can't keep up.
Young Domain Guard takes a different approach: it checks the age of the domain you're visiting using RDAP (Registration Data Access Protocol). If the domain was registered recently, you get a clear warning.
Features:
- ⚠️ Visual warning banner on suspicious pages
- 🔴🟢 Icon badge shows domain status at a glance
- 📊 Popup with registration date and exact domain age
- 📅 Configurable age threshold (1–365 days, default 30)
- 🌍 Smart multi-level TLD support (
- ⚡ Results cached for 4 hours — fast and lightweight
- 🏢 Well-known domains (Google, GitHub, Amazon…) automatically skipped
No data is collected. No external servers. Just RDAP queries and local caching.
