That fixed the problem. I had Torbutton installed, but never really used it so it was no trouble to disable it. Now, after repeated testing, CCleaner is wiping the cookies out as normal. Why Tor would be doing this is mysterious. Tor is supposed to be the "anonymizer" for browsing, and here it is keeping cookies. Whatever, this CCleaner bug can be considered closed, or at least understood, can't expect the good guys at Piriform to accommodate the weird behavior of every add on. Thanks a lot for your help QEM.

Yes, a number, but none that relate to cookies. Is there a known add on that would cause the cookies to be displayed in the Analyze window and apparently deleted when I Run Cleaner but not be deleted in fact? I have seen a number of cookie related threads and found none that match my conditions. I have now turned on the "delete cookies when I exit firefox" until CCleaner can do it.

CCleaner 2.21.940 Firefox 3.5.1 CCleaner will show the Firefox cookies in the analyze and they are gone once you run cleaner. If you do another analyze, nothing shows. But, when you open Firefox again and look at the cookies they are all still there. Close Firefox and run CCleaner and the old cookies will again appear ready to be cleaned. The only way I have discovered to delete the cookies is either manually from within Firefox, or set them to autodelete when you exit Firefox. Then they do not appear in a CCleaner analyze. This is OK, but I lose any cookies I may want to save and I do not get the secure deletion that I would like with CCleaner. These are true cookies, not Flash cookies. Everything is checked under the Firefox section, in fact all boxes are checked in every location except the "advanced" area. Regards,
