A recent update to an ad block filter list now allows the uBlock Origin extension to block most of the known sites that perform port scans of your local Windows computer.

    IMO, system-level features like port scanning should at least require a browser-generated permissions prompt like sensible browsers have for camera and microphone access, if not non-existent from the APIs available to websites.

      I can’t think of a use-case where a third-party website would ever need to see what ports I have open on my machine.

        Exactly. Same with what extensions I have installed and most other information listed in the fingerprinting section of Panopticlick.

        It’s for browser/device fingerprinting and basically nothing else.
