For an easy way to block sites based on domain name just add them to 
/etc/hosts and map them to 127.0.0.1.

It depends on what it is, mostlikely something you want. It may be firefox 
downloading the database of blacklisted sites for the "Block reported attack 
sites" and "Block reported web forgeries" features so those thing will not 
work properly. It could also be an ad block or some other plugin downloading 
the ads database. It could be downloading or verifying SSL certificates. It 
could be the Bookmark sync feature, etc, etc.
