| In this case, it only toggles settings already baked in to the original software. That should not increase your attack surface unless the settings are poorly tested. Moreover, it would not decrease your privacy unless: 1. The number of people messing with the setting is very small, AND 2. The default for the setting gives you at least as much privacy as flipping it does. The second point is not often the case. For example, turning off WebGL provides 1 bit of info ("turned off WebGL"). Leaving WebGL on allows a website to measure your WebGL setup, which is typically far more revealing. Not everyone uses the same GPU hardware and screen, after all. In general, flipping a setting to off reveals 1 bit of information - but it might indeed be 1 bit that few others know of, thereby reducing your anonymity group in that respect. Leaving a setting on allows a website to probe you further and find out things related to the setting. See for example amIunique.org -- it tests 4 WebGL parameters, which, for me, have a similarity ratio of 1.17%, 0.94%, 2.68%, and 0.53%. Those are quite horrible numbers and would likely identify me uniquely unless they almost completely overlap. |
