Where did you find those instructions?

I assume that this is a cookie that is used by the web page to remember you. Each web server will use its own name for such a cookie.

If the cookie settings are correct and weren't changed by you and you aren't in Private Browsing mode then you should be fine.

Note that the instructions to enable Images and JavaScript (4b,c) and the SSL/TLS settings (5,6) have been removed in Firefox and no longer apply to current releases.
