IIRC, the trick is to time filesystem access and deduce you're running from RAM rather than disk, thus in incognito mode.

  Sucks for you if you got ramdisk/optane, or have fsync disabled, I guess.

  Interesting, if that's what they're using it should be possible to inject a JavaScript to replace the filesystem access function with a wrapper that induces delay.
