Comment 35 for bug 44062

Instead of always blocking a domain in the blacklist, we could say that cookies
for those domains are always host cookies. Only co.tv can set cookies for co.tv,
and those cookies will only get send back to co.tv.

I agree that shipping a list is static, but that's why i want most of in in a
seperate file. That could be updated using the extension mechanism if needed. I
don't think it is taht bad. domain systems usually change slowly. (after all, we
also ship with a static list of certificates)

My main point is that relying on the website authors to fix their scripts will
take ages. There must be something we can do in the meantime to fix most cases.
