Firefox Relay is a Firefox extension that lets you keep your email address private when filling out online forms. It does this by creating an email mask and forwards messages to your real email address to keep it hidden from companies you don’t trust. You can even disable or delete the mask when you no longer need it.

Why use a mask?

• Prevent spam
• Protect your real email address from data breaches
• Protect your real email address from being sold or shared
