Firefox Extension · Multi-Account Containers

Every client tenant.
One click. Zero mix-ups.

MSP Tenant Launcher opens each customer's Microsoft 365, Exchange, Entra, and SharePoint admin centers inside its own isolated Firefox container — so you're never one wrong tab away from the wrong tenant.

Firefox only. Requires Multi-Account Containers support, native to Firefox — no separate add-on needed.

How it works

Four steps. No re-typing URLs.

Add a tenant once. Every portal click after that lands in the right place, signed in, isolated.

1

Add a tenant

Type the company name. That's it — no setup wizard, no config files.

2

Sign in once

Opens that tenant's admin center in a brand-new, isolated container.

3

Launch anytime

Microsoft 365, Exchange, Entra, SharePoint — one click each, already signed in.

4

Stay isolated

That tenant's cookies never touch another client's tab, or your own.

Security

We built this to hold as little as possible.

  • ✓
    No passwords, ever.There's no password field anywhere in the extension. Microsoft handles every sign-in, on Microsoft's own pages.
  • ✓
    No Microsoft tokens touch our servers.Sign-in happens entirely inside a real browser tab, bound to that tenant's container.
  • ✓
    Tenant data stays in your browser.Company names and container mappings live in local browser storage — never uploaded anywhere.
  • ✓
    Built on native isolation, not a workaround.Uses Firefox's own Multi-Account Containers system — the same mechanism the official container add-on uses.
