To anonymize ourselves, we must know what common values are used for specific points of measurement by servers. Unless we set up our own website (such as this) how else will we know we are increasing our anonymity? Turning everything off, or disabling plugins is a unique data point in itself; I am not sure we'd want to avoid leaking our plugin configuration as if that is the default, we are then a very unique data point. Instead, we would have to know what values are common, then report those to servers. Edit: Also, the cited Firefox plugin doesn't seem to spoof the client's display resolution correctly[1]. With such plugins, I can imagine our profiles become increasingly unique, as it may present potentially numerous combinations of metrics to servers that are not typical in the wild.
