I don't think the request is sent anywhere, why would dnsmasq send it to 
itself? 

Since you used no-resolv, I guess the request is handled locally according 
to docs:


   Also  permitted  is a -S flag which gives a domain but no IP ad‐ dress; 
   this tells dnsmasq that a domain is local and it may an‐ swer queries from 
   /etc/hosts or DHCP but should never forward queries on that domain to any 
   upstream servers.  --local is a synonym for --server to make configuration 
   files clearer in this case.


perhaps guys can correct me.

I have said it already: since you send everything to 8.8.8.8
why do you need explicitly configure any domain to query 8.8.8.8 ?

Why did you specify that domain at all? 

Why did you set server= and address= with firebaseio.com?
