TrustGuard - Email Scam Detector Firefox

TrustGuard - Email Scam Detector

Automatically scans Gmail, Yahoo Mail, Outlook, AT&T/BellSouth, and other webmail for phishing and scam patterns.

Features & Capabilities

TrustGuard is your second pair of eyes on every email.

Scammers don’t need to hack your computer. They trick people into clicking bad links, sending money, or sharing passwords. TrustGuard helps you slow down, spot the warning signs, and make a safer decision — before it’s too late.

━━━━━━━━━━━━━━━━━━━━ WHY PEOPLE INSTALL TRUSTGUARD ━━━━━━━━━━━━━━━━━━━━

• Automatic protection — scans emails as you read them, no extra steps • Plain English — tells you what’s wrong and what to do next (no jargon) • Color-coded risk — green, yellow, orange, or red at a glance • Action warnings — alerts before you click links, reply, download attachments, or call numbers in risky emails • Built for real people — simple, readable, and designed with older adults and families in mind

━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━

  1. Open your email in Gmail or Yahoo Mail
  2. TrustGuard analyzes the message on your device
  3. You see a shield next to each sender and a clear warning if something looks off
  4. Click the shield for a simple explanation and recommended next steps
You stay in control. TrustGuard explains the risk — you decide what to do.

━━━━━━━━━━━━━━━━━━━━ WHAT TRUSTGUARD CATCHES ━━━━━━━━━━━━━━━━━━━━

• Fake invoices and payment requests • Gift card and wire transfer scams • “Your account is suspended” phishing • Bank, Amazon, and brand impersonation • Inheritance and lottery scams • Urgent pressure tactics (“act now,” “final notice”) • Requests for passwords, SSNs, or verification codes

━━━━━━━━━━━━━━━━━━━━ YOUR PRIVACY COMES FIRST ━━━━━━━━━━━━━━━━━━━━

• All email analysis runs locally in your browser — on your device • TrustGuard does not read, store, or sell the contents of your emails • No account required to use core protection • Optional family dashboard sync is OFF by default and sends metadata only (never your email body) if you turn it on

━━━━━━━━━━━━━━━━━━━━ WORKS WITH ━━━━━━━━━━━━━━━━━━━━

✓ Gmail (mail.google.com) ✓ Yahoo Mail ✓ Chrome and Firefox

━━━━━━━━━━━━━━━━━━━━ WHO IT’S FOR ━━━━━━━━━━━━━━━━━━━━

• Adults who want extra protection against phishing and fraud • Adult children helping parents stay safe online • Anyone who’s ever thought, “Is this email real?” before clicking

━━━━━━━━━━━━━━━━━━━━ IMPORTANT ━━━━━━━━━━━━━━━━━━━━

TrustGuard is a safety assistant, not a guarantee. Always use your own judgment before sending money or sharing personal information. When in doubt, contact the company or person directly using a phone number or website you find yourself — not one from the email.

Install TrustGuard and read your email with more confidence.

Is TrustGuard - Email Scam Detector Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

TrustGuard - Email Scam Detector requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
