Chrome and Edge allow access to motion sensor data by default as well. Edit: Both the desktop and mobile browsers.

  The user has to perform an action to initialise the Generic Sensor API, just as they do with sound. That's just a click or a keypress, but you can't get sensor data without it.

    I can access some basic sensor data on default Edge without any confirmation. All it takes is some sneaky activation hidden in a navlink. Motion Sensor: Allow (default)

      Sure, but that's still a user action. The point is that the browser can't read anything simply by the user landing on the page - the user has to do something to enable it, even if they're not aware of the consequence of that action. This stops most malicious usage.

        How often do you visit a website and not do anything? As in not even move your mouse around or scroll.

          I don't think you can use pointer move events to enable sensors, but I'd need to test that to be sure.
