Get rid of Facebook ads

I'm seeing ads all over my news feed or timeline. How do I remove them?

Facebook ads will never appear as banners in the center, top, or left column of Facebook web pages. If you're seeing banner ads in these locations, or ads that flash or play sound automatically, you probably have adware. To remove it, review the add-ons or toolbars that you've enabled for your browser and disable any plugin that promises special browsing abilities (like timeline themes or seeing who's viewing your timeline).

To disable browser add-ons:

Mozilla Firefox
Tools > Add-ons > Extensions


Safari
Safari > Preferences > Extensions


Google Chrome
Window > Extensions


Internet Explorer 8
Tools > Manage Add-ons > Toolbars and Extensions
