The advanced properties you are referring to are only sent by the server in the set_cookie header. They restrict the use of the cookie by date, protocol, etc. This means the client knows when it needs to send the cookie and more importantly when it should not send the cookie.

When you use the cookie-editor to change these advanced parameters, you overrule the settings that the application has send and therefor change whether or not Firefox should send the cookie when doing a new request. It will not send the advanced parameters to the server as it only uses the advanced parameters to determine when to send the cookie and when not to internally.

Wireshark will however show the advanced parameters sent by the server in the set_cookie header and you can filter on them. Here is an example:

http.set_cookie contains ""
