Im trying to halt fingerprint tracking, whoever designed Firefox's privacy.resistFingerprinting rule makes fingerprinting even more prevalent.

With privacy.resistFingerprinting set to FALSE, my resolution is reported : 1920x1080x24, set to TRUE its 1920x968x24

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

Who in Firefox decided this config rule? and what is the logic behind it? Looks like intentional sabotage to make peoples browsers more trackable.

Whilst leaving resistFingerprinting set to TRUE, How can I force my resolution to the more generic 1920x1080x24?

Is there another setting in about:config I can change? if there isnt, where can I request this feature? Id rather not resort to an extention for something so small like this.

You are not meant to use maximized windows with RFP, this is why they are created unmaximized.

Fingerprinters check the whole browser fingerprint and never just one thing like screen size alone. All those 1080p screen users without RFP are uniquely identifiable by other means but this is not reflected in the statistic. You are better off with RFP even if it increases your uniqueness in these kinds of tests.

zeroknight, your reply makes zero sense.

Firstly, I am aware fingerprinting is a collection of attributes.

Secondly, The "Other things"(aka attributes) point you raised in your post are irrelevant, however, they actually only makes your point worse - By making our browser resolution more identifiable, you are creating overall more uniqueness in the total set of "things".

Fingerprinting relies upon noticing "things"(attributes) that deviate from the generic.

Its a statistical fact that most PC/Laptop users operate in full screen mode within a range of common resolutions, Thus by matching this its harder to uniquely fingerprint us.

I backed up this point in my first post with factual stats.

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

RFP is working counter productively - We want to blend with the 1 in 6 group, but RFP is pushing us into 1 in 6000 group.

Fingerprinting protection does not make you blend in, it is like wearing a Guy Fawkes mask in public. The details of the mask are unimportant as long as everyone wears the same mask.
