The short version
- The browser extension drops a fresh alias into any signup form in one click — no visiting the dashboard, no copy-paste. Click the badge, and a private address appears in the field.
- It’s on Chrome, Firefox, and Edge (plus their cousins like Brave and LibreWolf), and it works on every plan once you sign in with a magic link.
- It makes aliasing a habit by removing the friction — the whole reason people give up on using a fresh address everywhere.
The single biggest obstacle to using aliases everywhere is effort: opening the dashboard, generating an address, and pasting it in, every single signup. The email alias browser extension removes that friction entirely. It spots the email field on any signup page and, with one click, fills it with a brand-new alias that’s already forwarding to your inbox and saved to your account. This guide covers what the email alias browser extension does, how to install and sign in, the three ways to create an alias with it, and how it keeps your browsing private.
What the Email Alias Browser Extension Does
The email alias browser extension is a small add-on for your browser that brings alias creation to wherever you’re signing up. When it detects an email field on a page — the kind on almost every web form — it shows a small badge next to it. Click the badge and it generates a fresh email alias, copies it to your clipboard, and fills it straight into the field. You never leave the page.
That’s the whole idea: turn a multi-step chore into a single click, so using a unique address per site becomes effortless instead of aspirational. It’s the front door to the same alias system you manage in the dashboard — every address the extension creates shows up in your account, forwards to your real inbox, and can be disabled or organised later. Think of it as the fastest way to do what our guide on creating an alias describes, without breaking your flow.
How to Install It
Installing takes a moment from your browser’s add-on store:
- Open your browser’s extension store. The extension is available for Chrome (from the Chrome Web Store), Firefox (from Firefox Add-ons), and Edge (from Edge Add-ons).
- Add it to your browser. Click Add, and a small toolbar icon appears — the badge you’ll use to sign in and manage things.
- Pin it if you like. Pinning the icon keeps it visible so it’s one click away.
Because it’s built on the modern extension standard, it also works in browsers based on the same engines — Brave, Vivaldi, and Arc alongside Chrome, and privacy-focused builds like Tor Browser, LibreWolf, and Mullvad alongside Firefox. Support for Opera and Safari is on the way. Whichever browser you use day to day, there’s very likely a version that fits.

Signing In
Once installed, you connect the extension to your account so the aliases it creates belong to you. There are two ways to sign in:
- Magic link (every plan). Enter your email in the extension’s popup and confirm the login link, just like signing in to the website. This works on every plan, including the free tier, so anyone can use the extension.
- API key (Premium). If you prefer, paste a Premium
ea_live_API key into the extension’s options. This is handy for power users who already work with the email alias API.
For most people the magic-link sign-in is all they need, and it means the extension isn’t a paid-only tool — free users get the one-click convenience too. Once you’re signed in, the extension remembers you, and you’re ready to start creating aliases on any page.
Three Ways to Create an Alias
The extension gives you three ways to mint an alias, so you can use whichever fits the moment:
- The inline badge. A small badge appears next to the email field on a signup form. Click it and a fresh alias fills the field. This is the default and the fastest.
- A keyboard shortcut. Press
Ctrl+Shift+E(Cmd+Shift+Eon a Mac) to create an alias for the current site without reaching for the mouse. - The right-click menu. Right-click on a page and choose “Create EmailAlias for this site” from the context menu.
All three do the same thing — generate a random alias tied to the site you’re on — so it’s simply a matter of preference. The badge is great when you’re filling a form, the shortcut suits keyboard-driven browsing, and the right-click menu is there when you want it. Each one leans on the same alias generator behind the scenes. In practice most people settle on the badge for everyday use and reach for the shortcut when they’re moving fast, but having all three means there’s never a signup form where creating an alias feels like a detour — whatever way your hands happen to be working, a fresh address is one action away.
What Happens When You Click
When you create an alias with the extension, a few things happen at once, instantly:
- A fresh random alias is generated and labelled with the site you’re on, so you’ll later know which alias belongs to which signup.
- It’s filled into the email field and copied to your clipboard, so it’s ready whether the form wants a click or a paste.
- It’s saved to your account, already forwarding to your real inbox, and visible in your dashboard like any other alias.
- Revisiting a site reuses its alias. If you come back to a site you’ve already made an alias for, the extension recognises it and reuses the same address rather than creating duplicates.
The net effect is that signing up somewhere new costs one click more than usual, and in exchange your real address never touches the form. Over months of browsing, that tiny habit builds the same labelled, per-site map of aliases you’d get from careful manual work — except you barely noticed doing it.
Managing Aliases From the Popup
The extension isn’t only for creating — its popup is a mini dashboard. From the toolbar icon you can search your aliases, see which one belongs to the site you’re on, and jump to the full dashboard when you need more. If an alias starts attracting junk, you can act on it without leaving your browser — the same disable switch is available so a noisy signup is one tap from silence.
Premium users get a little more in the popup: the option to pick a verified custom domain as the default for new aliases, and per-alias spam allow/block controls. But the core loop — create, find, and manage aliases from the toolbar — is there for everyone. It means the extension isn’t just a shortcut for making addresses; it’s a lightweight control panel you carry with you as you browse.
Privacy and Permissions
An extension that sees the pages you visit deserves scrutiny, so it’s worth being clear about what this one does and doesn’t do. It reads only what it needs to find and fill email fields — the form’s input attributes — not the content of the pages you browse. It doesn’t load remote code: everything it runs is bundled into the extension itself, so there’s no hidden script pulled in later. And its whole job is to reduce what sites learn about you, by putting an alias between you and the form instead of your real address.
This matters because autofill tools have a mixed reputation for privacy. The design principle here is minimalism: touch as little as possible, ship no remote code, and exist only to keep your real address off the forms you fill. Combined with the tracker-stripping and spam protection your aliases already get, the extension keeps the convenience while staying on the right side of privacy.
Plans and Browsers
Here’s the quick reference for who can use what, where.
| Item | Details |
|---|---|
| Live browsers | Chrome, Firefox, Edge (plus Brave, Vivaldi, Arc, Tor, LibreWolf, Mullvad) |
| Coming soon | Opera, Safari |
| Sign-in | Magic link (every plan) or an ea_live_ API key (Premium) |
| Free plan | One-click alias creation, popup management, disable |
| Premium extras | Custom-domain default, per-alias spam allow/block, sender display name |
The short version: the extension’s core value — one-click aliases on every signup — is free once you sign in, and Premium layers on custom domains and finer control for people who want them.
Why the Email Alias Browser Extension Matters
It’s easy to underrate a one-click tool, but the email alias browser extension addresses the single reason most people fail to protect their inbox: they don’t keep it up. Using a unique address per site is a great idea that collapses in practice, because opening a dashboard and pasting an address, dozens of times a week, is more effort than anyone sustains. Privacy habits don’t fail because people stop caring; they fail because of friction. Remove the friction and the habit sticks.
That’s the real function of the extension. By living inside the web browser where signups actually happen, it makes the private choice the easy choice — the fresh alias is now less effort than typing your real address, not more. Over a year, that flips your exposure completely: instead of one real address scattered across hundreds of sites, you accumulate hundreds of single-purpose aliases, each traceable and disposable, built up a click at a time without any discipline required. When a site leaks or a signup turns spammy, you already have a dedicated address to shut off, because the extension quietly created one at the moment you signed up.
It also lowers the barrier to starting. Someone who would never manually alias every signup will happily click a badge, and once they see how painless it is, the behaviour spreads to more of their accounts. In that sense the extension isn’t just a convenience feature; it’s the thing that turns aliasing from a power-user practice into an everyday default. The full details and install links live on the browser extension page, but the point is simple: the best privacy tool is the one you’ll actually use, and removing friction is how you get there.
Final Thoughts
Aliases only protect you if you actually use them, and the thing that stops people is friction. The email alias browser extension removes it: one click, one keyboard shortcut, or one right-click, and a fresh private address lands in the form while your real inbox stays out of it. It’s on the browsers most people use, it works free with a magic-link sign-in, and it doubles as a pocket dashboard for managing what you create. Install it, sign in, and the next time you hit a signup form, let the badge do the work — you’ll have a clean, per-site alias without breaking stride, which is exactly how good privacy tools should feel.
And because everything it creates lands in the same account you manage on the web, nothing about the extension locks you in or hides your data away. The addresses it mints are ordinary aliases: you can rename their labels, reroute them, disable them, or export them alongside every alias you’ve made by hand. The extension is simply the fastest on-ramp to that system — a way to build the habit at the exact moment it matters, on the page where you’re signing up. Add it once, and the good behaviour takes care of itself from there.
Frequently Asked Questions
What does the EmailAlias browser extension do?
It brings alias creation to wherever you’re signing up. When it detects an email field on a page, it shows a small badge next to it; click the badge and it generates a fresh alias, copies it to your clipboard, and fills it into the field — without leaving the page. Every alias it creates is saved to your account, forwards to your real inbox, and can be managed later. In short, it turns the multi-step chore of making a unique address per site into a single click.
Which browsers is it available on?
It’s live on Chrome, Firefox, and Edge, installed from each browser’s add-on store. Because it’s built on the modern extension standard, it also runs in browsers based on the same engines — Brave, Vivaldi, and Arc alongside Chrome, and privacy-focused builds like Tor Browser, LibreWolf, and Mullvad alongside Firefox. Support for Opera and Safari is on the way. Whichever browser you use day to day, there’s very likely a compatible version.
Is the browser extension free?
Yes, the core feature is free. You sign in with a magic link — entering your email in the extension’s popup and confirming the login link — which works on every plan, including the free tier, so one-click alias creation isn’t paid-only. Premium adds extras in the popup, like choosing a verified custom domain as the default for new aliases and per-alias spam allow/block controls, and lets you sign in with an API key instead if you prefer.
How do I create an alias with the extension?
Three ways, whichever suits the moment. Click the inline badge that appears next to the email field on a signup form; press the keyboard shortcut Ctrl+Shift+E (Cmd+Shift+E on a Mac) to create an alias for the current site; or right-click on the page and choose ‘Create EmailAlias for this site’ from the menu. All three generate a random alias tied to the site you’re on, fill it into the field, copy it to your clipboard, and save it to your account.
What happens when I click to create an alias?
Several things at once, instantly: a fresh random alias is generated and labelled with the site you’re on, it’s filled into the email field and copied to your clipboard, and it’s saved to your account already forwarding to your real inbox. If you return to a site you’ve already made an alias for, the extension recognises it and reuses the same address rather than creating a duplicate. Your real address never touches the form.
Is the extension safe for my privacy?
It’s designed to be minimal. It reads only the input attributes it needs to find and fill email fields — not the content of the pages you browse — and it loads no remote code, since everything it runs is bundled into the extension itself. Its entire purpose is to reduce what sites learn about you by putting an alias between you and the form instead of your real address, which is the opposite of what a data-hungry add-on would do.
Can I manage my aliases from the extension?
Yes. The popup doubles as a mini dashboard: you can search your aliases, see which one belongs to the site you’re on, disable a noisy one on the spot, and jump to the full dashboard when you need more. Premium users also get a custom-domain default and per-alias spam allow/block controls in the popup. So the extension isn’t just a shortcut for creating addresses — it’s a lightweight control panel you carry as you browse.
Does it work with my custom domain?
Yes, on Premium. If you’ve added and verified your own domain, the extension lets you set it as the default so new aliases are created on your domain rather than the shared one — giving you branded addresses created with the same single click. On the free plan, aliases are created on the built-in domain. Either way, everything the extension makes appears in your dashboard and can be managed there like any other alias.
