Newsfeed Eradicator for Safari.
Newsfeed eradicator blocks the distracting Facebook newsfeed, but keeps the zombie-less functionality of Facebook. Newsfeed eradicator for Chrome was originally created by Jordwest.
I appreciated the Chrome extension a lot, but I use safari for it's power management. I did not replace the newsfeed with quotes as they got annoying after a while. It only removes the newsfeed.
