Use Netscape 8.12 Site Controls feature
Happy New Year 2007, rigtx! sorry I have not responded for several weeks.
You may want to take a look at the Site Controls feature of Netscape 8.12 browser and set up the sites that will allow cookies and block cookies from other sites. Click on Options from the Tools menu and click on Site Controls. from the Site Controls box and on the Site List tab, you can specify which sites will accept or reject cookies. Or you can specify which sites can be added onto the "I Trust this Site" list or "I Dont Trust This Site" list. The feature is a little more complicated than in previous versions of Netscape. I, too, am learning how to use the Site Controls feature of Netscape 8.12. Sites that are listed on the "I Don't Trust This Site" list, NO cookies from the "untrusted" sites list will be accepted.
personally I like the Cookie Manager feature where you can specify what sites the browser will accept or reject cookies. Cookie Manager is not featured in Netscape 8.x. It was featured in Netscape 7.x browsers and also in Firefox & Mozilla/Seamonkey browsers.
