TempMailGrab Chrome Extension

Generate a throwaway inbox from any browser tab without leaving the page. One-click copy, form autofill, and instant OTP detection — all from the Chrome toolbar.

Add to Chrome → Free, no account required. Works in Chrome, Edge, Brave and other Chromium browsers.

What the extension does

  • Toolbar popup — click the TempMailGrab icon to open an instant inbox overlay without navigating away from the current page.
  • One-click autofill — detected email fields on the active page can be filled with your disposable address in a single click.
  • Live OTP badge — when a verification code arrives, the extension icon shows a badge so you never miss it, even on a different tab.
  • Multiple addresses — keep several inboxes pinned in the popup; switch between them without reloading.
  • Zero tracking — the extension communicates only with tempmailgrab.com; no analytics, no third-party calls.

Why we built it

Switching between the TempMailGrab tab and a sign-up form is the biggest friction point for desktop users. The extension removes it: your disposable address and incoming mail are one click away on any page, with no context switch.

Prefer no install?

The web app at tempmailgrab.com works in every Chromium browser right now. Pin the tab and use it alongside any sign-up flow — instant inbox, OTP extraction, live sync, nothing to install.
