I use ClickToPlugin Safari Extension, but i don't know if this is pertinent for fixtracking. 

ClickToPlugin prevents Safari from launching plug-ins and replaces every plug-in object by a placeholder labeled by the name of the blocked plug-in. Clicking this placeholder loads the original plug-in object. Which plug-ins are blocked can be specified in the preferences. In addition, ClickToPlugin features several control lists to specify objects that should never be blocked or that should be hidden from view instantly. Check the Settings section for complete details on customizing ClickToPlugin.
