Keeping Javascript from leaking browser/system information

[Greyhat Harry]

I know virtually not a thing about javascript other than the fact that it's interpreted and mostly used for evil purposes, but having a programming background, I recalled my TRS-80 Model I Basic days, and I figured there may be certain statements available to Opera's implementation of the language that could potentially be parsed out so that they won't be used at all by the script. Kind of like the classic "mem" which reveals whatever amount of memory's available to the program, and failing to use it would render it unable to tell one way or the other about this particular aspect of the system.

I started using Proxomitron many moons ago, about the time I came across another app (now defunct and virtually useless, unlike good ole' Proxo) called Multiproxy, and I even managed to interface them together, but not once did I ever touch javascript, only html, thus all I needed was a lil push in the right direction
