I've used ccleaner for years and am very happy with it; I used it on win7 recently without a problem. But now I've installed it on a brand new install (factory settings) and... it shows some cookies, but not all. So I can't 'keep' certain cookies, because they don't show up in the list. What can I do to fix this?? browser: Firefox 9.0.1 thanks
