There's always something about this that confuses me. I thought I understood but now I can't quite get it straight in my mind.
I've got the PDF Browser plug-in in /Library/Internet Plug-ins. I've also got the AdobePDFViewer plug-in in the same location. Safari displays PDFs using the Adobe Viewer and my other browsers display PDFs using the PDF Browser plug-in (Schubert). It all works fine, but I can't remember why it works this way.
