1. There appear to be cookies still in Safari that Cookie doesn't recognize. For example, after removing all tracking cookies using Cookie, Safari | Preferences | Privacy shows cookies from cloudfront.net, imrworld.com, janrain.com, plus a few others. A bunch of google cookies are there. For sure the ones I listed are tracking cookies. How do I get Cookie to recognize and delete them?
2. The Cookie Databases tab have a bunch that are Type= Chrome Extension. Why won't Cookie delete them?

I just upgraded to the purchased Cookie product. How can I remove the free browser plug-in? It isn't listed in the Safari Extension list, nor any place else I can find.
