Unlike Gmail's built-in warnings that only catch known threats, Email Phish Protection gives YOU complete control: • Proactive Protection: Block suspicious links before Google identifies them • Zero False Negatives: You control what's trusted, not an algorithm • Lightweight: Doesn't slow down Gmail loading or performance • User-Friendly: Simple interface suitable for all technical skill levels • Powerful: Catches sophisticated phishing techniques that slip past filters ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📋 REAL-WORLD EXAMPLES Example 1 - Popup Mode Protection: You receive a "password reset" email claiming to be from PayPal. You click the link, and immediately a dialog appears: "Email Phish Protection: You are about to visit: http://paypa1.fake-site.com" You notice the "l" in PayPal is actually the number "1" - it's a phishing site! You click Cancel and delete the email. Example 2 - Warning Banner Alert: An email from "support@microoft.com" lands in your inbox (notice the typo in Microsoft). Before you even read it, a massive red banner appears at the top: "⚠️ CAUTION: NON-TRUSTED SENDER - This email is from microoft.com which is not in your trusted list." You immediately recognize it as suspicious and report it as spam. Example 3 - Whitelist Convenience: You add "amazon.com" to your trusted whitelist. Now all your legitimate Amazon order confirmations and package tracking links work normally with green underline, while fake Amazon lookalike domains are still blocked. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔧 TECHNICAL SPECIFICATIONS • Works exclusively on mail.google.com (Gmail) • Requires Chrome 88 or later • Only requires "storage" permission for saving preferences • Manifest V3 compliant for maximum security • No external dependencies or libraries • Cross-browser compatible (also available for Firefox) • Lightweight: Under 50KB total size ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ❓ FREQUENTLY ASKED QUESTIONS Q: Will this break my legitimate emails? A: No. Simply add trusted senders to your whitelist and their links will work normally. Q: Does this replace Gmail's phishing protection? A: No, it complements it. Use both for maximum security. Q: Can I temporarily disable it? A: Yes, click the extension icon and toggle it off, or add the sender to your trusted list. Q: What if I need to click a link urgently?

Q: Will my trusted list sync across devices? A: Yes, if you're signed into Chrome with sync enabled. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🆘 SUPPORT & FEEDBACK Need help or have suggestions? • Report bugs on our GitHub repository • Request features through GitHub Issues • Check documentation for troubleshooting …
