Firefox 111 Now Includes Email Alias Service Firefox Relay (How to Enable)

Starting with the release of Firefox 111 stable version this week, the Firefox browser now includes its email alias service, Firefox Relay, without the need for users to install the Firefox Relay browser extension.

Firefox Relay is an email alias service officially launched by Mozilla, providing users with proxy email addresses for registering or receiving emails from various internet services to hide their real email addresses. Firefox users need to log in to their browser account to use this feature.

However, Firefox users currently need to manually enable Firefox Relay:

1. Load about:preferences#privacy in the Firefox address bar.
2. In the opened Privacy Settings page, go to the Logins and Passwords section.
3. Check the “Enable Firefox Relay service for Firefox Password Manager” option (see screenshot).

Once enabled, Firefox Relay will display the option “Protect your email address. Add Firefox Relay” in the email field. Mozilla notes that sometimes Firefox may not detect email fields effectively, and therefore may not display this option. In this case, users can manually create email aliases in the Firefox Relay panel.
