@patrickleavy Vivaldi's built-in Tracker and Ad Blocker is designed to block privacy invasive trackers no matter what method they use, including ones using fingerprinting. However, rather than breaking useful APIs that websites can use legitimately, in order to to try to prevent fingerprinting, it just blocks the tracker. Legitimate websites can continue to use the APIs for the purposes they were designed for. https://vivaldi.com/blog/shared-networks-tracking-fingerprinting/In general, websites that try to terrify you about the implications of fingerprinting, are either owned by the makers of a product whose tracker blocker works by trying to use heuristics to detect trackers that use it (rather than just blocking trackers outright), or they are heavily biased towards that being the desired approach, even though it can break websites that use the APIs legitimately.https://vivaldi.com/security/common-questions/#privacytests
