How do I install the Firefox Relay Extension on Firefox Desktop?

Extensions or Add-ons are small software applications that customize and add functionalities to your browser. To learn more about extensions for Firefox, check this page.

Why use a mask?

With an email mask, you can get a temporary and disposable email address that lets you register for websites or newsletters without exposing your personal information. It covers up your original email address to protect it from abuse, helping you keep your identity and your inbox safe from unwanted emails, scams, and data leaks. A masked email address cannot be traced back to the real address, making it a great option for when you sign up for something online or share your contact information with someone you don’t fully trust.

What does the extension do?

The Firefox Relay extension helps you automatically generate a mask when registering on a website by clicking the Firefox Relay icon that will appear in the email address field. Without the extension, you must go to your dashboard to generate your mask and copy and paste it manually.
