Maybe worth reminding in connection with the article: https://panopticlick.eff.org/ https://panopticlick.eff.org/ - how many bits of identifying information your browser leaks from its configuration itself. Even on a fresh profile with none of the privacy-leaking stuff like cookies or cache.

Turning off Javascript moves me from being unique and fingerprintable, to being 1 of 161,000. This is with Chrome in incognito.

  How well does this work - in other words, how identifying is the absence of such information? (The third alternative would be to spoof the information on each request, but I don't know how well that would work, and it could cause other problems.)

    Most fields won't report with javascript disabled. In those fields "no javascript" reveals 1.86 bits about you, and 1 in every 1.33 browsers has it disabled.

You can measure fonts using JS to avoid having to have flash to do font based fingerprinting, eg http://www.lalit.org/lab/javascript-css-font-detect/ http://www.lalit.org/lab/javascript-css-font-detect/. There's also the option to attempt to set the font and then get the style of the element and see if it's using the new font (works only on FF and Opera IIRC), eg http://www.quirksmode.org/dom/getstyles.html http://www.quirksmode.org/dom/getstyles.html).
