Policeman is like RequestPolicy, only much better (and it imports RequestPolicy's rules). I haven't tried uBlock/uMatrix yet, but if you like RequestPolicy do give Policeman a try.
Policeman is awesome and is now replacing RequestPolicy for me - thanks for mentioning it. I can't see it available for Chrome yet, which means I have to stick to HTTPSwitchboard I guess.
