It would be great if we could be provided with the option to change our Username for the Firefox Relay email masks. When a new email mask is generated on Firefox Relay, I am provided with an email address with a completely random username that I could not modify. I would really love to have the option of modifying the username of the email masks.
Take the Duck Duck Go email protection feature for example, you can set-up your own duck.com email address. Perhaps something similar could be done with the mozmail.com email masks in Firefox Relay.
