Firefox is sending my ".domain.tld" cookies when I go to sub.domain.tld.
How can I make sure that the browser only sends cookies of ".sub.domain.tld" and not ".domain.tld"?

You cannot. If you set a cookie on
.domain.tld
it will be sent todomain.tld
and all subdomains.Although this may be unrelated to your problem, take a look at sstatic.net - where the Stack Overflow family of sites host their static resources.
