@jmaris Afaik, Chrome does not, but there are ways using fingerprinting (https://www.bleepingcomputer.com/news/security/google-chrome-extensions-can-be-fingerprinted-to-track-you-online/). However, I’d be very surprised if that was the case here. Because they don’t need to resort to such things. They’re already sure effective ad/tracker blockers cannot run in Chrome going forward because they’ve made it impossible for them to do so (see https://www.androidauthority.com/google-chrome-manifest-v3-changes-3386506/).
