Firefox Relay is a free browser add-on developed by Mozilla Corporation for the Chrome platform. It offers a simple and effective solution to protect your real email address and maintain your online privacy.

With Firefox Relay, you can easily create email masks that forward to your true inbox. This means you can generate unique, random aliases to use when signing up for accounts, apps, or newsletters. By using these aliases, you can keep your real email address hidden, reducing the risk of spam and unwanted emails.

One of the key features of Firefox Relay is the ability to block aliases. If you find that an account is sending unwanted email or spam, you can block the alias associated with that account. This ensures that no further emails from that alias will be forwarded to your inbox.

Additionally, Firefox Relay allows you to delete aliases when you no longer need them. This gives you full control over the accounts and services that have access to your real email address.

Overall, Firefox Relay is a valuable tool for anyone concerned about their online privacy. By providing disposable email aliases, it helps you maintain control over your inbox and reduce the risk of spam and unwanted emails.
