Information
These settings configures what is allowed to be tracked by websites to which the browser connects.
Rationale:
Enabling do not track instructs the browser to send an optional header in HTTP requests made from the app that indicates a preference not to be tracked by websites. This optional header is voluntary in nature, having no method to enforce adherence and providing no guarantee that web sites will honor the preference. However, a large number of websites do honor it so there is privacy benefit in enabling it.
Solution
To establish the recommended configuration, set the following values to true:
privacy.donottrackheader.enabled
privacy.trackingprotection.enabled
privacy.trackingprotection.pbmode
Type about:config in the address bar
Type privacy.donottrackheader.enabled in the filter
Ensure the setting is set as prescribed.
Type privacy.trackingprotection.enabled in the filter
Ensure the setting is set as prescribed.
Type privacy.trackingprotection.pbmode in the filter
Ensure the setting is set as prescribed.
OR
Open the mozilla.cfg file in the installation directory with a text editor
Add the following lines to mozilla.cfg:
lockPref('privacy.donottrackheader.enabled', true);
lockPref('privacy.trackingprotection.enabled', true);
lockPref('privacy.trackingprotection.pbmode', true);
Default Value:
privacy.donottrackheader.enabled=false
privacy.trackingprotection.enabled = false
privacy.trackingprotection.pbmode = false
Additional Information:
privacy.trackingprotection.pbmode is only available on FF43 and up (ESR is at v38). Leaving here because it does no harm and this benchmark is likely to be used by many for standard version.
