Wouldn't it make more sense to tell you if a site you had visited was breached and when? What if you never go back to a site you used your common credentials on? It seems wrong to just say this site has been hacked when you go there (what major site hasn't been at some point?). With Have I Been Pwnded data, FF should be telling you if any username/password combos it has remembered have shown up on any lists, which sites you've used them on, tell you to change them and remind you not to use the same combos across sites.
