Hello, i have the issue that times are displayed in UTC as long I have enabled fingerprint protection. Is there a way to exclude time zones or to manually set the timezone I want?

I found this in about:config: privacy.fingerprintingProtection.overrides: string

Can I override the settings for the timezone?

Disable privacy.resistFingerprinting and instead enable privacy.fingerprintingProtection and change privacy.fingerprintingProtection.overrides to +AllTargets,-JSDateTimeUTC. Note that if you disable Tracking Protection for a site then it will also disable fingerprinting protection.

Thank you, have tried the setting. Now js.Date() returns the proper time from my Timezone. Note that coveryourtracks.eff.org (I cannot tell how reliable this site is) is telling me that "Your browser has a nearly-unique fingerprint" when I have set privacy.resistFingerprinting to true, or to false (multiple combinations of addons tried). I guess +AllTargets,-JSDateTimeUTC means, to enable all aspects of fingerprinting protection except JSDate (I was not able to google it or find it in the docks)?
