Safari extension to monitor 3rd party activity?
Is there anything like Mozilla's "Lightbeam" (https://addons.mozilla.org/en-US/firefox/addon/lightbeam/) for Apple's Safari on the desktop? Mozilla released the add-on to allow users to monitor the other sites that monitor you, but Apple rejected them from the iOS platform, but there's nothing so far for their desktop version and was wondering if anybody knew of something similar?
