Reducing Panopticlick fingerprint score #372

I have been looking to reduce the Panopticlick fingerprint score through experimenting with various settings.

So far I have found that these 2 reduce the bit score:

user_pref("general.useragent.override", "Mozilla/5.0 (Windows NT 6.1; rv:52.0) Gecko/20100101 Firefox/52.0"); // Panopticlick -3.9
user_pref("privacy.resistFingerprinting", false); // Panopticlick -0.7

With these two applied at the end of the user.js I achieve a score of 7.9 in Firefox.

I still can't find a single browser for which "Is your browser accepting Do Not Track commitments?" to show something different from "no". I have asked EFF by email many days ago but no reply at all.

Out of the box TBB with security slider set to max security shows a score of 6.57 bits. I wonder which particular prefs may help to achieve that in FF too and if there are any settings which may help to reduce it even more.

Any ideas?

Changing useragent can break Websites and make you more unique so i wouldnt recommend that

From what I've read setting "privacy.resistFingerprinting" to "false" causes the Firefox window not to be set to a generic size (at start), thus making your Firefox more unique if you have it set to a custom width/size.

At this point I'm beginning to doubt the Panopticlick score values... (just my two cents ofc ;))

In TBB it is privacy.resistFingerprinting;true
Can you suggest a better privacy test?

Panoptclick gives its results over the pool of the browsers that have been submit to the test. That's a subset of common browser: just look at the results in an indicative way (feel happy when you are not unique) and try to blend in the biggest pool possible.

It seems like the whole window size protection is still broken in Firefox. At least on 60.2.2esr.
