I hate looking at online ads that I am never, ever going to click on, and I’m pretty aggressive about using adblocking software like Adblock Plus to avoid seeing them.  Recently, I’ve noticed that quite a few Facebook ads are getting around the default Adblock Plus filterset, so after a bit of experimentation, I’ve found that adding the following three custom rules to Adblock Plus cleans things up quite a bit:

facebook.com##div#pagelet_ego_pane_w
facebook.com##div.ego_section
facebook.com##div.pagelet_platform_engagement
