Like many others I have been waiting for word on an update to Pith Helmet. I gave Glimmerblocker a try but as a Little Snitch user Glimmerblocker made life hell. My prayers have been answered in the discovery of AdBlock for Safari - works incredibly well, as good as the Firefox version. And now I couldn't care less whether Pith Helmet is updated or not. I have a working FREE solution that won't break every time an update is released.
