I was poking around in my about:config, and I noticed this:
browser.geolocation.warning.infoURL
I'm surprised I've never noticed that before and I am considering adding something about it in the anonymity tutorial considering what this is used for. Have any of you tweaked this setting for privacy purposes? I can't believe I've didn't know about this setting.
EDIT: Just discovered a few other geo-location settings in firefox. Looks like I'll be doing some more tweaking, and I'll probably be updating my tutorial.
