Browser extension
Sign up for anything
without giving them your inbox.
A disposable address, filled into the form for you, and the verification code caught and pasted back — without leaving the page you are on. Free, open source, and no account needed to start.
Availability
The code is Manifest V3 and runs in Chromium already — it is the store listing that is pending.
Same build as Chrome. It will land alongside it.
What it does
Codes, the moment they land
It watches the inbox and reads the code out of the mail itself. A banner shows it with Copy and Autofill, so you never open a mail client to retype six digits.
Fills the right field
It scores the inputs on the page rather than grabbing the first one, so the address goes where the signup form actually wants it.
Addresses that stick around
Save the ones you care about and pick them straight from the popup, instead of generating a fresh address and losing the last one.
Codes in the Dynamic Island
On a Mac with Atoll installed, a code arriving while you are in another app shows up at the top of the screen instead of behind a window.
Getting started
Install it from Firefox Add-ons.
Open the popup and generate an address, or pick a saved one.
Sign up. The extension fills the field and catches the code.
The details
What leaves your machine
Your addresses and your mail stay on your device. Nothing you read or type on a page is sent anywhere. The one thing reported back is an anonymous install count — a random ID, the version, and your browser and OS — and you can switch it off in the extension's settings.
Licence and source
GPL-3.0 from v1.5.1. Read it, change it, share it — and anything built on it stays open too. Nothing is minified or obfuscated: the files inside the add-on are the source files, so you can unpack it and read exactly what you installed.
Stop handing out your real address.
It takes one click to install and nothing to set up.
