About this extension
🛡️ Phishing Detector Add-on
A smart, proactive browser extension that warns you before phishing pages can trick you — powered by a crowdsourced phishing URL feed.
✨ Key Features
🔄 Live Threat Feed (Every 90 Minutes)
Fetches the latest phishing data from PhishStats every 90 minutes. Ensures you're protected with near real-time updates.
🕵️♂️ Smart Domain Matching
Instead of matching full URLs (which can easily change), it uses eTLD+1 domain extraction (like
🧠 URL Normalization
Cleans up and standardizes URLs by stripping query parameters, protocol differences, and trailing slashes — so phishing attempts using URL obfuscation don't slip through.
⚠️ Full-Screen Warning Page
If a user visits a suspicious page, they’re shown a clear, fullscreen warning with:
- ⏰ Last update time of the threat feed
- 🧷 A list of known phishing links matching the current domain
- 💬 A friendly reminder that the list is community-sourced
🔒 Two Clear Choices for the User
- ✅ Ignore Warning for Today
Suppresses future warnings for this domain for the next 24 hours.
- 🚪 Proceed Anyway
Bypasses the warning just for the current session. Warnings resume when the browser restarts.
🚫 No False Alarm Loops
Domains you choose to ignore (for the day or session) are remembered. You won’t be warned again during that period.
🔍 Lightweight & Privacy-Respecting
- 📁 All data is stored locally
- 🌐 No personal data leaves your browser
- 🛑 Doesn't track your browsing
📥 Auto-updating Threat Database
- No need for manual configuration
- Always stays current in the background
