And here's our open-source tool that we've been using to do all these privacy measurements: https://github.com/citp/OpenWPM/

We'd love to see pull requests or just other people using our tool for new interesting findings.

These are great posts!

I've recently discovered https://www.browserleaks.com/ which has tests for several sorts of browser fingerprinting.

Edit: The follow-up post cites the W3C draft on fingerprinting: "elimination of the capability of browser fingerprinting by a determined adversary through solely technical means that are widely deployed is implausible". But there is a simple strategy. Just compartmentalize online activity, such that everything that a particular persona does can be safely linked by adversaries. And it's fun!
