I have FaceBook and FireFox and I was looking for the Ad On for FireFox called FaceBook Activity Remover. It lets you Remove every Post you ever made on FaceBook and your Wall. I go to my Tools and Ad Ons and FireFox can not find it and yes I type it in the Ad On Search Box. I know I can Delete anything one by one. But I want to do a Full Activity Delete. Can anyone help?
