Browser Extension Issues

Common problems with the AliasFleet browser extension and how to fix them

2 min read
Updated May 11, 2026

The extension isn't logged in / keeps logging out

Extension sessions are separate from your web app login. If the extension shows you as logged out, sign in directly through the extension popup.

If sessions keep expiring, check that your browser isn't set to clear cookies or site data on close — this can log the extension out on every browser restart.

The extension session was revoked

If you revoked extension sessions from Settings → Security, those sessions are immediately invalidated. You'll need to sign into the extension again.

The extension can't create an alias

Make sure you're signed in to the extension and your account hasn't hit the alias limit for your plan. Check your usage at Billing.

The extension isn't detecting email fields

The extension relies on recognising email input fields on web pages. Some sites use custom input components that aren't detected automatically. In those cases, copy an alias manually from Aliases and paste it into the field.

The extension is asking for unusual permissions

The extension only requests permissions needed for its core function — detecting email fields and injecting aliases. If you're seeing a permissions prompt that seems unexpected, make sure you're installing from the official source and not a third-party copy.

Revoking all extension sessions

If you think your extension credentials were compromised, go to Settings → Security, find the Extension Sessions section, and revoke all sessions. Then reinstall the extension and sign in again with your current credentials.

Still having issues?

Contact support with your browser name and version, extension version (visible in the extension popup), and a description of what's happening.

Frequently Asked Questions

Why does the extension keep logging me out?

Extension sessions are separate from your web app login and may expire if your browser clears cookies on close. Check your browser settings and sign in directly through the extension popup.

Can I use the extension on multiple browsers?

Yes, install the extension on any supported browser and sign in with your AliasFleet account. Each browser will have its own separate session.

Why isn't the extension detecting email fields on some websites?

Some sites use custom input components that aren't standard email fields. In these cases, copy an alias manually from your Aliases page and paste it into the field.

What permissions does the extension need?

The extension only requests permissions to detect email input fields and inject aliases. It does not access your browsing history or other personal data.

How do I revoke extension access?

Go to Settings → Security, find the Extension Sessions section, and revoke all sessions. Then reinstall the extension and sign in again with fresh credentials.
