Recursive DOM Objects enumeration test
We have a mozmil test which enumerates DOM objects: https://gitweb.torproject.org/boklm/tor-browser-bundle-testsuite.git/blob/HEAD:/mozmill-tests/tbb-tests/dom-objects-enumeration.js
We should convert that to a mochitest test included in the browser sources tree, and do it recursively.
arthuredelstein has the beginning of a recursive version: https://github.com/arthuredelstein/fingerprint/blob/master/fingerprint.js
