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.
