#30605: accept-language header leaks browser localization --------------------------------------+-------------------------- Reporter: sysrqb | Owner: tbb-team Type: defect | Status: new Priority: Medium | Milestone: Component: Applications/Tor Browser | Version: Severity: Normal | Resolution: Keywords: | Actual Points: Parent ID: | Points: Reviewer: | Sponsor: --------------------------------------+--------------------------
Comment (by acat): I think what happens in desktop (with lang other than en-US) is that on first navigation there is the prompt asking whether to spoof to english, if the user accepts then it sets the `privacy.spoof_english = 2` pref. Then, the pref listener in `toolkit/components/resistfingerprinting/RFPHelper.jsm` sets the `intl.accept_languages = en-US,en`. In Android I don't see `privacy.spoof_english` is not set, and then even if set manually to 2, `intl.accept_languages` is not changed. I wonder what is failing here... Changing `intl.accept_languages = en-US,en` manually works, and then the `accept-language` header is spoofed correctly. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/30605#comment:2> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
