Browser Fingerprint Test
Sites do not flag a hash. They flag signals that disagree: the clock, the language, the platform, and the WebRTC address.
What this test does that others don't
Other testers: A green hash and a uniqueness percentage.
This test: No uniqueness score. The contradictions sites act on come first.
Other testers: Brave and Firefox with fingerprint resistance look broken.
This test: Named as a privacy browser, on purpose coarse.
Other testers: Twenty pages, one value each.
This test: Clock, language, platform, and WebRTC on one screen.
Checking
Comparing the signals sites actually compare.
A library hash is collected afterwards. It is an id, not a uniqueness score.
Library ids
These are ids from two libraries. They are not a uniqueness score, and they are not uploaded.

Questions people actually ask
Does a hash mean I am unique?
No. A hash is an id two libraries can compute. It does not say how rare you are, and this page does not print a uniqueness percentage. Those numbers are marketing.
What actually gets a session flagged?
A contradiction. The clock says one country and the IP says another, the user agent says Windows while the platform does not, or WebRTC shows a second public address. A green hash with those mismatches is how people get a false sense of safety.
Why does Brave or Firefox look strange here?
Brave, Firefox with fingerprint resistance, and Tor coarsen values on purpose so sites cannot follow the browser. That is a privacy browser, not a broken one, and it is not scored as a bot.
