AntiPhish - Phishing Detector

🛡️ 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 example.co.uk, malicious.com) to catch tricky subdomain tricks like:

hxxp://secure-login.microsoft.verifybadsite.com

🧠 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.
