2-click social media buttons not usable on heise.de

Edit Subject

Ghostery (ver. 2.8.3) prevents in FF (16.0) to use the social media opt-out buttons (2-click buttons, introduced by heise.de).

The problem is: normally Ghostery shows an image and the js-code of the social media button is blocked. But I can activate it manually by click on it.
When I now have an opt-out solution, an inactive button is shown. Only after clicking it, it will be activated and the social media live button is loaded. This prevents Ghostery, which means: there will be shown nothing at all. Inclusive the ghostery activation button/image. So I have no chance to activate the social media function.

For example try it here with activated Ghostery: http://www.heise.de/newsticker/meldun...
