Firefox cookies not being deleted

I have several sites I have in the keep but all others are not being deleted at all. I can run and clean and than go back into cookies and it shows me cookies to be deleted still. It is not deleting cookies because if it was they would not be showing in the list as cookies to be deleted. As you can see by the attached image that the cookies are still showing as to be deleted and that is after running it twice.

Latest version 4.03.4151

Firefox 18.0.2

Right-clicking and clean cookies in Applications\ Firefox cleans all mine ok.

CCleaner 4.03, Win7 x64

Try a CC 4.03 clean reinstall.

May also help to install ad blocking software in your browser, and use a HOSTS file such as MVPS.org HOSTS file.

are you running an advertising cookie opt-out add-on (such and TACO) as those add-ons create the cookies (as do not collects) at the launch of your browser

No I am not running any sort of cookie add-on at all. I tried to do something different and search for the cookies in Firefox that CCleaner is reporting needs to be deleted and none of them show in that list at all. So I looked for cookies that are in Firefox and should be deleted and did not see some of them. It appears that Ccleaner is not actually looking at the Firefox Cookies Database to see what needs to be deleted or not.

Ok I found the bug with it. The problem is even though I am ONLY using Firefox for my browser some old temporary internet files still existed for IE even though I reset it. So once manually deleted the cookies to clean is now empty. So the real issue is Ccleaner is not cleaning the Internet Explorer 9 cookies or temporary files at all.
