The first time this new function was ever mentioned was last May, when Mark Zuckerberg himself announced that Facebook is working on it. It has now been confirmed by the company’s CEO, David Wehner. This new tool’s function will be to allow the FB user to clear her or his history on the social website. This includes groups joined, content liked, apps installed etc. At least in theory – knowing Facebook, they will probably keep on spying on us nevertheless.
