I don't understand why you would need Better Privacy, doesn't this addon pretty much do the same thing ?

TrackerBlock provides focused Flash cookie control

Like Better Privacy, TrackerBlock removes Flash cookies (as well as HTML5 objects, which Better Privacy does not currently handle). The difference is that TrackerBlock focuses on objects from 450+ companies who are engaged in user tracking across sites, who typically write local objects on a third-party basis (i.e. you visit Site abc.com, and you get a Flash cookie from ad network def.com). Better Privacy can be set to delete all Flash cookies. In some cases, this means you are deleting even first-party Flash cookies, which can be useful in saving settings or performing other functions on websites that you visit. So if you want zero Flash cookies of any kind, you might want to use Better Privacy. If you want zero Flash cookies of any kind, you might want to use Better Privacy as well.
