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.
