Keeping Javascript from leaking browser/system information

[Greyhat Harry]

Thank you JJoe! that's exactly what I needed. Sorry also about the delay.

I understand there's no silver bullet when it comes to this, but figuring things out on a per-page basis (while following the pattern you've provided), is good enough for the kind of task I have before me. Truth to be told, there's hardly any website for which I'd bother turning javascript on (the page I've linked to isn't one of them, yet it's technically very similar to the one I'm actually interested in), and everything else I handle with bare, minimum functionality.

As touching uniqueness, not a problem in this case either, though I personally lean towards full secrecy, for even plausible deniability has limited value where the rule of law's been systematically trodden under foot.
