Safe Mail Link Check — Where does that link go?

When you click a link in Gmail, Outlook on the web, or Yahoo Mail Japan, this extension pauses the very first navigation and shows a confirmation dialog with the link's real destination. Everything runs locally on your device — nothing is ever sent anywhere. Free, no account required. Most phishing emails rely on one trick: the text you see is not where the link actually goes. This extension is a small confirmation gate that shows you the real destination before the link opens, so the decision stays yours. WHAT THE DIALOG SHOWS - Link text (what the anchor visually says) - Destination (the real hostname) - URL (the full URL) - Only when applicable, formal warnings: - Displayed text and real destination do not match - Unencrypted connection (HTTP) - Raw IP address instead of a domain name - Punycode (potentially deceptive internationalized domain) - URL shortener The dialog never declares a link "safe" or "dangerous" — it only presents the facts. WHEN IT HELPS - You tend to click email links reflexively - You are worried about fake delivery, bank, or credit card emails - You want an unobtrusive safety check on a family member's or coworker's PC - You simply want one extra look at where a link really goes KEY FEATURES - Never opens links automatically — there is no "Open" button. Even "Allow this time" does not open the link; it opens only when you click it again yourself - Never rewrites anything — the link's href and your email content are left untouched - Asks every time — "Allow this time" applies to that one URL, in memory only. No permanent allowlist is ever created - Choose what to check — toggle Gmail / Outlook / Yahoo Mail Japan individually, and add any webmail domain of your own - Add or remove the current site directly from the toolbar popup - Fully keyboard operable (Escape to cancel) - No account, no cost SUPPORTED SITES - Gmail (mail.google.com) — checks links inside the email body - Outlook on the web (outlook.live.com / outlook.office.com / outlook.office365.com) — checks links to external domains - Yahoo Mail Japan (mail.yahoo.co.jp) — checks links to external domains - Any webmail site you add in the settings — checks links to external domains PRIVACY - Does not collect, store, or transmit your email content, click history, or browsing history - All checks run entirely inside your browser. No server, no analytics, no telemetry - The only thing saved is your settings (on/off toggles and added sites) - No ads IMPORTANT NOTES - This extension is not a blocker and does not guarantee that any destination is safe - The warnings are format-based hints and cannot catch every dangerous link - Whether to open a link is always your own decision RELATED PRODUCTS - Safe Privacy Mask — masks strings that look like personal or confidential data, on your device, before you paste into AI chat Both are built on the same principle: pause once, let the user decide, never act automatically.
