Hello there Patrickdrd.

Hi there you have the settings viewed from your computer itself, it could be that you have not filled in properly so that there is a time to come there but incoming messages adapt when coming on your computer machine so that there is a wrong time and or display date?

I solved it, it should have been this: privacy.resistFingerprinting = true

nope, Windows

well I had set it to true actually and I reverted to false is what I did, and I had set it to true because of some thunderbird hardening suggested I had read
