In plain words
Firefox Relay is a privacy tool that generates random email aliases to protect users' real email addresses. The aliases automatically forward incoming messages to the user's actual inbox, helping shield personal information from hackers and unauthorized tracking. It works as a browser extension and appeals to anyone concerned about online privacy and account security. The service is open source and designed for everyday internet users and developers.
