As part of a research project on web browser security we are currently taking a “census” of browser installations. We hope you’ll agree to participate.

If you do participate, a small snippet of JavaScript will collect your browser’s settings and send them to our server. We will record a cryptographic hash of those settings in our research database. We will also store a non-unique cookie (saying only that you participated) in your browser. We will do all of this immediately if you click this link.

(If you want to see in advance the Javascript code we run on participants’ machines, you can read it here.)
