This is a very functional cookie manager with an intuitive user interface. A very nice feature is that you can export/import your whitelist and blacklist. It even has built-in help. Thanks to the developer for this great add-on!

One thing that's not clear in the help is whether whitelisting *.foobar.com also whitelists foobar.com — or do I have to whitelist both to whitelist all pages from that site?

Also, does whitelisting *.foobar.com allow cookies from deeper sub-domains, such as bar.bletch.foobar.com — or do I need to whitelist *.*.foobar.com to allow cookies from that domain?
