I've been trying alphas of Firefox 3 and noticed that CCleaner does not seem to clean cookies for it. Also, in the Options/Cookies menu, the cookies that I do have are not shown at all. I am using Firefox 3.0a8pre, CCleaner v2.00.491, and Windows XP. I am not sure if this is a bug, a problem with my computer, or if Firefox has changed its cookie handling on us. If it is a Firefox change, CCleaner will eventually have to be updated in the next few months.
