About this extension
Shop with confidence. HasTrust is a free scam checker and price checker that gives you an instant, evidence-backed verdict on any store or product — before
you pay.

Is this site legit, or a fake store? Is this seller trustworthy? Is the price a real deal or a fake discount? HasTrust answers all three while you browse.

HOW IT WORKS
HasTrust runs quietly in the background. On a safe store you see a calm green check. On a risky one — a brand-new lookalike domain, no valid HTTPS, or a
seller with scam and fraud reports — you get a clear warning before checkout, not after your money's gone.

Click the icon for the full picture:
• Trust score built from public reviews, complaints and scam reports
• Scam and fraud report check
• HTTPS certificate and domain age (new domains are a classic scam signal)
• Third-party ratings — Trustpilot, BBB, Sitejabber, ScamAdviser and more
• Community trust votes from other shoppers
• On product pages: the live price, plus cheaper or better alternatives

PRIVACY FIRST
HasTrust reads only the page's domain (e.g. example.com) to look up a verdict — never the full URL, page contents, your cart, or any personal data. The
full product URL is sent only when you click "Check this product" yourself, with tracking parameters stripped. No accounts. No tracking cookies. Nothing
sold.

Free. Works on Firefox desktop.
