#17175 closed defect (user disappeared)

Site is able to detect locale in some way

Severity: Major Keywords: tbb-fingerprinting-locale

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
intl.accept_languages;en-US, en
capability.policy.maonoscript.sites;about: about:addons about:blocked about:certerror about:config about:crashes about:home about:memory about:neterror about:plugins about:preferences about:privatebrowsing about:sessionrestore about:srcdoc about:support blob: chrome: mediasource: moz-safe-about: resource:
