If you have given up on Facebook and wish to remove your “digital footprint” by permanently deleting your Facebook account, you may find that last time Facebook only allows users to “deactivate” their accounts, leaving their information intact.

However, now it is possible to delete your account permanently via this URL.  Simply click on the “Submit” button and follow the given instructions.  Your account will be permanently deleted within a few days.  This method is official and should be complete, i.e. no need to delete individual photos, comments, messages or items from your profile or anywhere else on Facebook.
