How it works
Share Relay email masks instead of your true email address to protect your email inbox, as well as your identity.
Get the extension
Download the Relay extension for Firefox. Generate email masks automatically wherever you enter your email address online.
Create a new email mask
As you browse, the Relay icon will appear where sites ask for your email address. Select it to generate a new, random address that ends in @mozmail.com.
Manage your email masks
Sign in to the Relay dashboard to keep track of the email masks you’ve created. If you find that one receives spam or unwanted messages, you can block all messages or even delete the mask, right from the dashboard.

We don’t recommend using masks when you need your identity verified or for very important emails or those where you must receive attachments. For example, you’d want to share your true email address with your bank, your doctor, and your lawyer, as well as when receiving concert or flight boarding passes.
