When you’re looking at profiles on Facebook, is there a giant gap in the center (the left side of the right column)? If so, it’s probably due to their latest CSS update, which the Adblock Plus subscription list has not yet adjusted for. Odds are it will be fixed really soon, but until then, here’s a hack to fix it: ∞

• The hard way:
  1. Go to the chrome directory in your Firefox profile directory. If you’re not sure where that is, it’s probably easiest to find it by:
     1. Windows users, go to Windows Run (type the Windows key + r) and then enter:
        %APPDATA%\Mozilla\Firefox\Profiles\
        Mac users, open:
        ~/Library/Application Support/Firefox/Profiles/
        Linux users, open:
        ~/.mozilla/firefox/
     2. Then, open the directory that has “default” on the end of it. (Odds are there will only be one).
     3. Then, open the “chrome” directory.
  2. Create a file called userContent.css
  3. In Notepad, edit that file to have just this in it: .profile .right_column_container .profile_sidebar_ads { height: 1px; }
  4. Save the file and restart Firefox
• The easy way:
  1. Save this userContent.css fix file to the directory found in step 1 of the hard way above. If you already have a userContent.css file there, you’ll need to append the contents of it.
