Firefox Relay, created by Mozilla, is a service that generates unique, disposable email aliases to protect your real email address from spam, marketing lists, and data breaches. It acts as an intermediary, forwarding emails sent to your alias to your actual inbox, while masking your primary email. The primary workflow involves using a browser extension or the website to generate a new alias when signing up for a service, then managing these aliases from a central dashboard. It works as a web service and a browser extension for Firefox, Chrome, and Edge, with plans for mobile app integration. Its most used feature is its ability to quickly generate a unique alias directly from signup forms with a single click. Email data is processed by Mozilla's servers for forwarding, and they clearly state their privacy policy regarding handling and deleting emails.

Why It’s Useful

Firefox Relay eliminates the pervasive problem of exposing your personal email address to potentially untrustworthy websites, drastically reducing spam and the risk of your main inbox being compromised in data breaches. For the online shopper constantly signing up for loyalty programs, it provides a safe way to receive order confirmations and discounts without flooding their primary inbox with marketing emails. For the digital freelancer, it allows them to register for various SaaS tools or client platforms using unique aliases, minimizing their digital footprint and enhancing security. The free tier offers 5 aliases, which is genuinely useful for managing personal sign-ups, while the premium tier offers unlimited aliases and a custom domain. Compared to SimpleLogin, Firefox Relay benefits from the trusted Mozilla brand and its integrated browser experience, making it particularly seamless for Firefox users. A power feature is the ability to easily disable or delete aliases that become compromised or receive too much spam, cutting off unwanted communication instantly. A non-technical person can easily set it up and generate their first alias in under 2 minutes.
