This is a reply received after emailing to firebase-support@google.com, which is the official firebase support email after gogle acquired firebase in late 2014.

From: firebase-support@google.com
In order to transfer ownership of a Firebase instance, we need you to do two things: add the new owner as a collaborator; then, fill in the form below and email it to us as written verification. This must be sent from the email address which owns the Firebase instance.

----------------- 
REQUEST TO TRANSFER OWNERSHIP
I authorize the Firebase team to make **** the owner of https://****.firebaseio.com effective immediately. I have added **** as a collaborator to verify the email address is correct and to certify that I am the current owner. I understand that I am effectively granting **** full read and write access to all stored data for this instance.
