Firefox Relay Premium allows you to register your unique Relay email domain so that you can create custom email masks on the fly without a phone or computer. This is especially convenient if you need to provide an email address when checking out at an establishment, and you don't want them to keep your personal email address. Custom masks are composed of three basic elements: a username (like shopping), that can indicate the specific use case for the mask; a unique email domain (like exampledomain), that you set up following the steps below; and the mozmail.com domain, that is shared by all Firefox Relay masks.
Create a Relay email domain
- Sign into relay.firefox.com to access your Firefox Relay Dashboard.
- In the Set your unique Relay email domain section, enter the domain name you want and click .
- You will see a green check mark if the domain name is available. Check the box to confirm your choice and click .
- After registering the domain name, you will see a confirmation message. Click to finish the process.
All set! From now on, when you visit a store or a website, you just need to provide whatever email username that comes to your mind accompanied by your Relay email domain handler (like shopping@exampledomain.mozmail.com), and it will automatically appear in your Relay dashboard once an email is sent to it.
