btw, Mozilla's Tracking Protection list doesn't use Google's SafeBrowsing service or list (which is malware list, not a tracker list). It talks to a Mozilla server, specified by in the "browser.trackingprotection.gethashURL" about:config pref: https://tracking.services.mozilla.com/gethash?client=SAFEBRO.... Mozilla's list is currently based on Disconnect's tracking list: http://services.disconnect.me/disconnect-plaintext.json.
