 Hello, Flagfox developer here. (please replace the CC to the support email
 address with a CC for this new account)

 I'm a little confused as to why this issue was posted here. Flagfox has
 not ever been able to show a flag when running under Tor, when things are
 properly configured. The addon is technically compatible with TBB, and
 some other functions do work, but Flagfox is fundamentally incapable of
 showing location information through Tor, as the entire purpose of Tor is
 to hide such information. Flagfox specifically asks Firefox/TBB for proxy
 info for a site before doing a DNS lookup (hitting the cache) to fetch the
 IP address to look up in an optimized and compressed version of Maxmind's
 IP location database. (there isn't another simple way to grab the IP used
 for a given resource) If Firefox/TBB is configured to only use its proxy,
 in this case Tor, and not do local DNS lookups, Flagfox will not kick off
 a new one. This is to avoid leaking DNS lookups and weakening the
 protection a proxy/Tor gives. (the detection code isn't perfect, but
 neither is the DNS backend Mozilla has that doesn't do this automatically)
 If there is some way to proxy a DNS request safely through Tor, I don't
 know a simple way to do that on my end. Do note that I am limited by what
 Mozilla APIs are available here.

 Here's an old stickied FAQ on this topic from the Flagfox support forum:
