Ed @addons.mozilla.org:

I am having some trouble with this addon. When used with the Disconnect addon or Firefox's built-in Tracking Protection and the Cookie AutoDelete addon, the Show Comments button at the end of each article on politico.com becomes non-functional. Are there conflicts among these items?

The facebook plugins needs the href field. So we're adding an exception for facebook plugins,
".*(facebook\\.)\\w{2,}.*(\\/plugins\\/).*", in 98d6b45.
