Is CCleaner keeping cookies from portable browsers?

CCleaner for Windows CCleaner Windows Help Requests

I use portable browsers (Pale Moon, Slim Browser and SlimJet). In SlimBrowser and SlimJet I use cookie protection add-ons. For Pale Moon such a thing does not exist so I need to keep all cookies, or delete all cookies manually to keep those I want to preserve. 

Before working CCleaner I need to know whether it will delete the cookies from the portable browsers, and if so, how to protect some of them. In the cookies section of the settings I find only cookies which are associated to the installed browsers (Internet Explorer plus two versions of Edge) - even though I know positively that most of these websites whose cookies are in the list - for example Facebook and Dr Windows - I have never used with any of these installed browsers.

The 3 Microsoft browser are listed under the 'Windows' Tab in CCleaners Custom Clean.

Other Browsers that you have installed are listed under the 'Applications' tab when you click on it.

For example Firefox here:

If the browsers are Chromium based then their cookies may be seen as Chrome cookies.

You can tell Custom Clean (but not Health Check) if you want particular cookies to be left alone, or if you want all cookies to be left alone, see this article:

If they're portable you'll need to use customlocation
