Facebook Ads

[Belarathon]

Given Joe's response to the "facebook ticker" thread, I've located the following userstyle to thwart facebook ads:
------------------------------------------------------------------

@-moz-document domain("facebook.com") {


.ad_capsule{ display: none !important; }
#ssponsor{ display: none !important; }
.nextstep{ display: none !important; }
.sponsors { display: none !important }
.invitefriends { display: none !important; }
.social_ad { display: none !important; }
#sidebar_ads { display: none !important; }
.sponsor { display: none !important; }
#feedwall_with_composer, #info_tab { width: 722px !important; margin-left: -180px; }
.story_content { width: 660px !important; }
.story_body {width: 665px !important; }
.photos_tab { width: 945px !important; }
.emu_sponsor,.house_sponsor { display: none !important; }

/* Block sidebar ads (+1.72 - 2009-02-20) */
.from_friend_story {width: 725px !important; }
.UIHomeBox_Sponsored, .profile_sidebar_ads { display: none !important; }

/* Hide sponsor from the home page (+1.74 - 2010-11-01) */
#home_sponsor_nile{ display: none !important; }

/* Block sidebar ads again and hide ads from the photo overlay as well (+1.75 - 2011-05-19) */
#pagelet_ego_pane { display: none !important; }
.fbPhotoTheaterGrid .adsContainer { display: none !important; }

-----------------------------------------------------------------

The script works perfectly. Does this give some clue how filters might be written to block the ads with Proxomitron?

Thank you,

Cary
