## Description

The unity-firefox-extension package could be tricked into destroying the
Unity webapps context, causing Firefox to crash. This could be achieved by
spinning the event loop inside the webapps initialization callback. Fixed
in 3.0.0+14.04.20140416-0ubuntu1.14.04.1 by shipping an empty package, thus
disabling the extension entirely.
