Firefox Helps You Hide (Your Emails)

Following several months of testing, Firefox users can now take advantage of the Firefox Relay email masking tool from within the browser to help preserve their online anonymity and boost security. 

What Is Firefox Relay? 

Firefox Relay from Mozilla is a Firefox browser extension that lets users keep their email address private when filling out online forms. It does this by creating an email mask (a forwarding email address that’s different to their real email address) and forwards messages to the user’s real email address to keep it hidden. Users can disable or delete the mask when it's no longer needed.
