It's better to switch off JavaScript. Try panopticlick with and without it.

i just tried but sadly it did not finish without allowing js on their site and for both of the thirdparty tests. It might would have finished if i would not have enabled this test though.

However, even if it would show better results then my user agent and accept header is apprently pretty unique anyhow. But why bother.. My ip addresses do not change that often.

yes, noscript is a must, however not enough against fingerprinting
