The Data Manager just uses the permission manager. So the same limitations and same principal policy generally applies e.g. http://test.com will block only unsecure cookie requests from test.com not from the domain and so on.

Thank you for the link, FRG.  I don't use the DM, nor the "Don't
allow websites that set removed cookies to set future cookies", so
I don't think the bug discussions apply.

I did, however, figure out the answer to my second question - if I
block all cookies, then allow them from e.g. https://aaa.bbb.ccc,
cookies from https://bbb.ccc are blocked, but aaa.bbb.ccc can set
cookies that say the domain is bbb.ccc - does that make sense?

I use the following strategy.  I do not block all cookies. Instead, I
allow cookies only from the domain of the Web site I requested.  I have
also blocked cookies from selected Web sites, primarily advertising
sites that might have cookies set by my select Web sites.

The key is that I located the file cookies.sqlite in my profile and
marked it as read-only.  All the cookies that get set as I surf the Web
are lost as soon as I terminate SeaMonkey.  That is, all of those
cookies are treated as session-only.

Sometimes, however, I want to keep a cookie.  Fortunately, that does not
often happen because the process is somewhat cumbersome.  To see my
process, go to <http://www.rossde.com/internet/cookies.html#doabout>.

Thank you for the response - but I'm asking a very basic question:
Does allowing cookies from a specific site allow cookies from "subsidiary" sites?  Same question when blocking cookies.

If you allow cookies from the second level domain, then they would be allowed from one of its specific third level domains as well.

Thank you.  Does the reverse apply - i.e. if I allow cookies from a
specific third level domain, are they allowed from the second level
domain?

No, not normally, unless you use a cookie handling extension that specifically allows that.  For my part, there is no way I want that to happen with a big domain.
