Mozilla's Firefox Relay email security plugin will soon be built into the web browser, allowing you to protect your privacy directly through Firefox.

After months of testing, Mozilla is ready to bring Firefox Relay to all Firefox Account users by making the email masking tool an integrated part of the popular web browser. This means that the once optional manual installation is now built in, making it easier for you to take advantage of it without having to install anything first.

The primary purpose of Firefox Relay is to create "email masks" that act as stand-in email addresses that you can use in place of your regular accounts. Once you create and use a mask, you can access it for as long as you want, but you can also delete it at any time and it will have no connection to any other addresses. Think of it as spontaneously creating a new email address that acts as a filter for account logins, surveys, etc. that require an email address to access.

This more direct integration allows any user with a Firefox account to use email masks directly from a website’s toolbar. Masks can be generated and managed in the Relay dashboard, and you can choose from your existing masks directly from the browser window (when the opportunity arises). Anyone signed up for one of Relay’s paid subscription options can also reply to emails anonymously, have unwanted promotional emails blocked, and more, depending on their tier.
