Hello,
if you ordered the exception list in the "top-level first order", e.g.
org.somedomain.its-subdomain
instead of
its-subdomain.somedomain.org
then handling cookies exception lists would become much easier: often cookies are sent from domains that (only) differ in the least significant domain level ('its-subdomain'). Changing the cookie treatment with a list in the actual ordering can then be VERY annoying. And this simple ordering changement would solve the without much work to implement it ..
Comments are welcome!
(Of course the same true for adblock lists etc. but we're in the firefox forum, right?)
