In Options -> Cookies, right-clicking in "Cookies to Keep" and selecting "Export" will save a list of hostnames, but there won't be any line breaks between the names. For example, if my Cookies to Keep list is:
1password.com
abcnews.go.com
accounts.google.com
it will export the list as a text file with the single line:
1password.comabcnews.go.comaccounts.google.com
and if I right-click Cookies to Keep and select Import, it will add a single entry with that name, which of course is useless.
If I've exported a large number of Cookies to Keep, and then I try importing that list, it will crash CCleaner immediately (probably because it doesn't expect a single site with such a large name).
If I hand-edit the exported cookies file to add line breaks between the hostnames, then I can import it properly.
