I was using torthe Tor browser (in safer mode in tails-5.2 with default settings, with no addon or any modification) to browse youtubeYouTube. While I was searching for pythonPython tutorials, it offered that in the language of my region. How did youtubeYouTube figure it out even in torTor?
Note: I used a fresh tails with no persistent storage or any other modifications. Also, I never searched youtubeYouTube in my language or watched any content of my region before. So youtubeHence, YouTube should have no knowledge of my language, isn't it? I tried multiple times rebooting tails and searched (with & without bridge) again only for pythonPython (nothing before that).Also Also, I tried resetting identity and different circuits. But every time it was offering contents in my language (along with englishEnglish).
How is it even possible? Is it a bug? Or google did Google perform a correlation? Or did webrtc/dns leak (torTor shouldn't have this issue)? Or cookie/javascript issues? Or ANYTHING ELSEanything else?
