It would be nice to turn network zones blocking on and off

subj.
I hate to say, but G00gle is inside My blocked zones.
Sometimes i need to fill out a f****ng captcha to register… Most of the capchas are G00based.
I must to remove G00 from blocked addresses manually each time.
Only two buttons would be enough - permit connect to address and/or do not permit to connect to it.
please vote!
