An e-mail mask is a forwarding address that you use when you want to keep your real e-mail address private. All emails that are sent to your masks will be forwarded to your real email address without revealing it.
Firefox Relay is a Firefox extension that keeps your real email address from companies you don’t trust.
You can permanently delete a mask or temporarily disable forwarding to stop receiving emails in your inbox.
If you’ve forgotten your Firefox Accounts password, reset it to a new password, then log in to Firefox Relay with your new password.
