Firefox Relay creates email masks that forward messages to your real inbox. It can help separate sign-ups and make it easier to shut off a source of unwanted mail. The service still processes routing information and the forwarded message ultimately reaches your normal mailbox, so use it with a clear recovery plan.

- Forward messages to a real inbox
- Disable masks that attract unwanted mail
Limitations
- Forwarded email still reaches your destination mailbox.
