Der Autor von PithHelmet hat nochmal eine neue Version des Werbeblocker-Safari-Plugins veröffentlicht.
Scheinbar hat sich da doch eine Menge unter Safaris Haube getan: Support for Safari 1.3 has been added. Unfortunately, there are many interactions with this new version of Safari. I believe these interactions are bugs in WebCore/JavascriptCore and I will try to isolate them and report bugs to Apple as necessary. In the meantime, the content collapsing feature is turned off by default to keep Safari stable.
