Using the Browser Extension

Using the Browser Extension

Install the AliasFleet browser extension, create aliases inside signup forms, and autofill them without leaving the page.

The AliasFleet browser extension makes a forwarding alias inside any signup form and fills it in for you, so your real address never goes into a site. Install it, sign in once, then click the AliasFleet icon inside an email field, pick a suggested alias, and it fills the field. Install, autofill, side panel, shortcuts, and Vault Lock follow.

What you need

An AliasFleet account and a supported browser (Chrome, Edge, Brave, Opera, Vivaldi, or Firefox).

How do I install the extension?#

Three quick steps, then it stays out of your way on every site you visit.

  1. Install from your browser store. AliasFleet is in the Chrome Web Store (Chrome, Brave, Opera, Vivaldi), Edge Add-ons (Edge), and Firefox Add-ons (Firefox).
  2. Pin the extension. Click the Extensions icon (the puzzle piece) in your toolbar, then the Pin icon next to AliasFleet.
  3. Sign in. Click the AliasFleet icon, then Sign in to AliasFleet. A secure browser window opens so you can sign in or confirm access.
  4. Check it connected. Your aliases, verified domains, and settings appear.

The extension runs on its own session token, separate from your web login, so signing out of the dashboard does not disconnect it. Managing and revoking sessions is covered in Browser Extension Sessions, not here.

How do I create an alias in a signup form?#

When a page has an email input, the extension puts the AliasFleet icon inside the right side of the field. Click it to open Quick Create.

What Quick Create does next comes down to your Creation Mode in settings:

Creation ModeBehaviour
Speed ModeGenerates an alias in your default style and fills the field in one click.
Smart Suggestions (default)Opens a popup with four naming formats plus any existing aliases for the site.
Manual OnlyOpens a small form so you type a custom prefix directly.
Data comparison table

Smart Suggestions gives you four styles: Site-Based (github-k8x2@afleet.me), Random Words (swift-falcon-42@afleet.me), Dated (github-2026-09@afleet.me, which dates the signup), and Category-Based (shopping-x7q9@afleet.me).

How do I reuse an alias for a site I already use?#

Click the inline icon and open Aliases for this Site at the top of the popup. Clicking an address fills it into the field, so you do not end up with a second alias when you sign back in or fill another form on the same site.

How do I create an alias when no email field is detected?#

Some forms use custom elements that never expose a standard email input, so the inline icon never shows up. Use the right-click menu instead:

  • Inside a text or email input: right-click the field and select Generate alias and fill. It makes an alias, fills the field, and copies it.
  • Anywhere on a page: right-click a non-editable area for Create alias for this site (tagged with the current tab domain), Quick random alias (no site attached), or Open AliasFleet Dashboard.
  • Keyboard: Alt + Shift + A makes an alias for the current site and copies it.

How do I manage aliases from the side panel or popup?#

The toolbar icon opens the full management view. On Chromium browsers (Chrome, Edge, Brave) it shows as a persistent Side Panel docked beside your browsing. Firefox shows a popup with the same features.

  • Account stats: alias count against your plan quota, forwarded messages this week, bandwidth used.
  • Quick Create card. Already filled in for the active tab domain: Website, Random Words, UUID, Keyword, Manual. Advanced opens multi-destination routing and instant category creation.
  • Search, filter, and sort. Search by prefix, note, or site domain; filter All, Active, Inactive; sort Newest first, Oldest first, Name A-Z; the site filter shows only aliases for the active tab.
  • Alias actions. Toggle forwarding, copy an address, or delete (double-click, then confirm Sure?). Switching an alias off drops its incoming mail at the gateway.

How do I use keyboard shortcuts?#

Three shortcuts cover the jobs you will repeat most.

ActionWindows / LinuxmacOS
Generate for Current SiteAlt + Shift + A⌥ + ⇧ + A
Copy Last Generated AliasAlt + Shift + C⌥ + ⇧ + C
Toggle Side Panel / PopupAlt + Shift + O⌥ + ⇧ + O
Data comparison table

To change them, open chrome://extensions/shortcuts (or edge://extensions/shortcuts), find AliasFleet - Email Alias Manager, and record a new combination.

How do I lock the extension on a shared computer?#

On a shared computer, turn on Vault Lock to encrypt the extension credentials in local browser storage. The key comes from a 4-digit PIN via PBKDF2 and never leaves your browser. The vault locks after 15 minutes of inactivity or when the browser restarts. After 5 wrong PINs in a row, local tokens are cleared and you sign in again with your account password.

  1. Open the extension and click the Settings gear.
  2. In the Security section, toggle Vault Lock on.
  3. Enter and confirm a 4-digit PIN.

For the full walkthrough, see How to Use Vault Lock in the Extension.

How do I change extension settings?#

Open the extension and click the Settings gear. You will find Auto-copy to clipboard, Enable inline button, Creation mode, Default style, Enabled suggestions, Show button on (All fields, Signup only, Exclude login), Popup theme (Match Site, Light, Dark), When Limit Reached (Block & Error, Rotate Existing, Upgrade Prompt), and Excluded Sites (with a Current button for the active tab).

How is this guide different from the extension sessions doc?#

This guide covers setup and day-to-day use: installing, creating aliases, autofill, the side panel, shortcuts, settings, and Vault Lock. Browser Extension Sessions covers the security side: what a session is, what access it has, and how to view or revoke connected extensions.

What if something goes wrong?#

Start with the quick fix that matches what you see.

ProblemFix

Frequently Asked Questions

The extension supports all Chromium-based browsers (Google Chrome, Microsoft Edge, Brave, Opera, Vivaldi) as well as Mozilla Firefox.

Click the AliasFleet icon in your browser toolbar and click 'Sign in to AliasFleet'. A secure authorization window will open where you sign in or confirm access to connect the extension to your account.

No. The extension only looks at the active tab's domain and visible form inputs when an email field is detected, so it can offer alias generation. It never reads webpage content, passwords, or forwarded email messages.

Yes. Any verified custom domains configured on your account are automatically available in the extension's domain selector alongside AliasFleet default domains.
