I'm not an avid fan of ccleaner anymore, as my experience w\ ccleaner is it isn't infiltrating Firefox to delete the passwords like it used to? or do I need a trip to sing-sing?
Yes it will. But if you look at the CCleaner window you should see a check box for this option to stop CCleaner from doing it. Also using something like Cookie Culler will stop it as well for sites that you mark to keep the cookies no matter what. they are protected.
