Firefox Relay review
A focused alias service for reducing spam and tracking, with limited outbound support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Firefox Relay creates email masks that forward messages to a real inbox without exposing the underlying address. It is aimed at people who want to reduce spam, limit email tracking, and avoid sharing their primary address with websites and other senders. The service includes a dashboard for managing and labeling masks, plus a browser extension for creating them on sites. It is available through the web, Android, and Chrome extension platforms.
The published plans show a free Limited email protection tier with five email masks, a browser extension, and tracker removal. Email protection adds unlimited masks, a unique Relay email domain, promotional-email blocking, and anonymous replies to forwarded messages. Email & phone protection adds phone masking, while Add VPN protection includes Mozilla VPN access alongside unlimited masks and phone masking. Paid tiers are presented as waitlist-only, so Relay suits buyers who value incremental privacy controls more than a broad sending platform.
Relay’s strongest focus is lightweight address masking rather than full email-account replacement. Masks forward incoming messages to a real inbox, and users can reply anonymously from a masked address, but the service does not support custom domains or new outbound messages. That makes it a practical choice for sign-ups, shopping, newsletters, and other situations where limiting exposure matters. Buyers who need to send fresh messages from aliases, connect their own domain, or manage a more complete alternate mailbox should choose a different email alias service.
