When a cookie is created it is possible to control its visibility by setting its 'root domain'. It will then be accessible to any URL belonging to that root. For example the root could be set to "whatarecookies.com" and the cookie would then be available to sites in "www.whatarecookies.com" or "xyz.whatarecookies.com" or "whatarecookies.com". This might be used to allow related pages to 'communicate' with each other. It is not possible to set the root domain to 'top level' domains such as '.com' or '.co.uk' since this would allow widespread access to the cookie.
By default cookies are visible to all paths in their domains, but at the time of creation they can be retricted to a given subpath - for example "www.whatarecookies.com/images".
I can't vouch for the valitidy of the explanation, but it does give a "warm and fuzzy" feeling about cookies.
Basically Firefox won't allow that, since every single cookie has a label to a specific domain name, called domain.
This is a basic security measure, or else anyone can create a website and steal your cookie name, which is called Session Hijacking.

Wow. That is an awesome information security site. I took a quick look at that and barely scratched the surface. I will definitely bookmark that and peruse it with great care, but I think it's going to take more than a few hours to really get into that. The details of web sessions are something I'm going to have to know eventually, but they are clearly very complicated. Thanks for the resource.
but the advertising WILL install "tracking cookies "
and they WILL send a list of all installed cookies to the site and any "affiliates" of theirs
in a utopian world cookies would not be a bad thing
But we DO NOT LIVE IN ONE .......
there is a reason i run
Ghostery
No-Script
Ad Block Plus
and disable some "java-script" in firefox
Yeah, that's the kind of information leakage I had suspected. So even if Google doesn't know my Yahoo email address, they know that I'm on Yahoo often enough to have cookies there.
As for Ghostery, Ad Block Plus, and deactivated Javascript - I run Firefox with those on an OS X machine, and many websites are not usable.
