Facebook Purity is an add-on for web browsers such as Firefox, Chrome and Safari that gives users absolute control over what kind of content is displayed in their Facebook news feeds. Using the Purity add-on, users can choose to hide any type of post, including posts by specific applications. As the Facebook platform becomes more developed, however, the company gives users more control over what items are displayed in their news feeds. As such, some users may no longer have a need for the Purity add-on.
