"TorButton has evolved to give considerable thought to fingerprint resistance [19] and may be receiving the levels of scrutiny necessary to succeed in that project [15]. NoScript is a useful privacy enhancing technology that seems to reduce fingerprintability."
"We identified only three groups of browser with comparatively good resistance to fingerprinting: those that block JavaScript, those that use TorButton, and certain types of smartphone.
"We should study what TorButton does, and see if we can integrate some of its features. We can also recommend it, NoScript, and Flashblock to users. We could suggest improvements to relevant addons, such as providing options for blocking third party but not first party content. (This doesn't strictly solve anything, but makes gathering the data more difficult, since the third party now relies on the first party to collect it.)
Unfortunately Flashblock does not appear to prevent Flash from reading and writing LSOs, so it's doubtful it can be relied upon to protect against fingerprinting.
