Browser Extension Issues

Fix AliasFleet browser extension failures step by step: missing extension, undetected email fields, broken autofill, blank popup, and expired extension login.

Most extension trouble falls into five buckets: the extension is missing or switched off, it cannot spot email fields, autofill does not fill, the popup opens blank, or the extension login has expired. Find the failure that matches what you see and work through its steps.

This guide covers extension failures only. For installing the extension and everyday use, see Browser Extension. For how extension sessions work and how to revoke them, see Browser Extension Sessions.

Before you start

You need an AliasFleet account and a supported browser: Google Chrome, Microsoft Edge, Brave, Opera, Vivaldi, or Mozilla Firefox. The extension must be installed from the official store (Chrome Web Store, Edge Add-ons, or Firefox Add-ons), never a third-party copy.

How do I fix the extension when it is missing, disabled, or will not install?#

No icon on your toolbar means the extension is not installed, is disabled, or is simply hidden from view. Browser updates and profile changes are the usual cause. Check your browser's extensions page, switch the extension back on if it is off, and reinstall it from the official store if it is gone entirely.

  1. Open your extensions page. In Chrome, go to chrome://extensions. In Edge, go to edge://extensions. In Firefox, open the menu, choose Add-ons and Themes, then Extensions.
  2. Look for AliasFleet - Email Alias Manager. If it is listed but switched off, toggle it back on.
  3. If it is not listed at all, reinstall it from the official store for your browser: Chrome Web Store, Edge Add-ons, or Firefox Add-ons.
  4. Pin it to the toolbar. In Chrome and Edge, click the puzzle-piece icon in the toolbar and pin AliasFleet - Email Alias Manager so it stays visible. In Firefox, right-click the extension and choose Pin to Toolbar.
  5. Reload the page you were testing on, then click into an email field to confirm the icon appears.

How do I fix the extension not detecting email fields?#

The extension looks for standard email input fields on the page. Some sites build their forms with custom input components that never register as email fields, so the extension has nothing to latch onto and no icon appears. That is a limitation of that site's form, not a broken extension, and the manual workaround below still gets the alias into the field.

  1. Click into the email field and wait a second to confirm the AliasFleet icon really is missing.
  2. Check the extension is signed in. Open the extension popup. If it shows a login screen instead of your account and aliases, sign in again.
  3. Reload the page and try once more. Single-page apps sometimes replace the form after the first load, which can drop the detection.
  4. Test the same field in another browser or on a simple site like a newsletter signup. If detection works there, the problem is that site's form.
  5. Use the manual workaround. Open the extension popup, find or create the alias you want, copy it, and paste it into the field. The alias works exactly the same as one the extension filled.

How do I fix autofill not working?#

When the icon appears next to a field but clicking it fills nothing, the field is usually waiting for you to click into it first, or a page script is getting in the way of the fill. Click into the field yourself before concluding the extension is at fault.

  1. Click into the field yourself first, then click the AliasFleet icon and choose Insert alias.
  2. If nothing fills, copy and paste instead. Select the alias in the extension popup, copy it, and paste it with Ctrl+V (Cmd+V on Mac).
  3. Reload the page and try once more. Single-page apps sometimes swap the field out after the first load, which the extension then cannot find.
  4. Try another website. If autofill works elsewhere, the issue is that site's form, not your extension.

How do I fix a blank popup or a popup that will not open?#

A blank popup, or one that will not open at all, usually means the extension's saved session expired or the browser put the extension to sleep to save memory. Signing in again, or restarting the browser, fixes it in nearly all cases.

  1. Sign in again through the extension. Click the toolbar icon. If you see a login screen, sign in with your AliasFleet account details. Extension sessions are separate from your web app login, so signing into the dashboard does not fix this.
  2. Restart the browser completely. Close every window and open it again; browsers suspend extensions to save memory, and a fresh start re-enables them.
  3. Reload the extension. On chrome://extensions or edge://extensions, click the reload icon on the AliasFleet card, then try the popup again.
  4. If the popup is still blank, reinstall the extension. Remove it from your extensions page, install it again from the official store, and sign in. Your aliases and settings live in your account, so nothing is lost.

How do I fix a login that expired in the extension?#

Extension sessions are separate from your dashboard login. They can expire when the browser clears cookies or site data on close, or after you revoked sessions. You will see a login screen in the popup instead of your aliases; the fix is to sign in again through the popup itself.

  1. Open the extension popup and sign in with your AliasFleet account details.
  2. Stop the browser wiping site data on close. Check your browser's privacy settings and make sure it is not set to clear cookies or site data when you close it; that setting logs the extension out on every restart.
  3. Check whether you revoked extension sessions. If you recently revoked sessions under Settings → Security in the dashboard, every extension session was invalidated at once. Just sign in again through the popup.
  4. Look for privacy tools doing the clearing. If logins expire after every browser restart even though the browser setting above is off, a privacy extension or a managed-profile policy may be wiping site data. Add an exception for AliasFleet's site if you can.

What do I tell support if nothing above works?#

If nothing above fixes it, contact support and include the details that identify your setup: browser name and version, extension version (shown in the extension popup), the website where it happens, and which of the five failures this matches.

Keeping a separate alias per site is what contains a breach to one address. If you want a refresher on why that matters, read One Email Alias per Website Keeps a Breach From Spreading.

Frequently Asked Questions

Extension sessions are separate from your web app login and may expire if your browser clears cookies or site data on close. Check your browser's privacy settings so it keeps site data between sessions, then sign in again through the extension popup.

Yes. Install the extension from the official store on each browser you use and sign in with your AliasFleet account. Each browser keeps its own separate session.

Some sites build their forms with custom input components that do not register as standard email fields, so the extension has nothing to detect. Copy an alias from the extension popup and paste it into the field manually as a workaround.

The extension asks only for the permissions it needs to detect email fields and insert aliases. It does not read your browsing history or other personal data. Install it only from the official Chrome Web Store, Edge Add-ons, or Firefox Add-ons listing.
