 Today I tried to search Google using localized Tor Browser. And I was VERY
 SURPRISED to see localized search results (though the page was in
 English). Some time after that I was far more surprised to see the page
 being redirected to the localized Google domain. I examined the headers
 using devtools and I haven't seen any signs of my locale in them. I
 examined the path, the exit node is not in my country. How could they
 detect it? This should be investigated and fixed.

 I use TBB 5.0.3.

 The settings are:
 extensions.torbutton.spoof_language;en-us, en
 extensions.torbutton.spoof_english;true
 extensions.torbutton.spoof_locale;en-US
 javascript.default_locale;en-US
 intl.accept_languages;en-US, en
 javascript.enabled;true
 noscript.global;false
