This addon has purpose similar to RequestPolicy and NoScript. It's different from the former in that it supports rules based on content type (for example, you can allow images and styles, but not scripts and frames for some sites) and some other data (it has a mini-language for writing advanced rules). It can also be set up to act as a blacklist, minimizing interference.

This add-on requires quite a lot of interaction from user to get things working.
Some sites will not work properly until you have allowed the required content.
