Does CCleaner have this problem while Firefox is still running or when all Firefox windows have been closed?

What is it that you want to clean from Firefox? For example: browsing history, cookies, cache of previously viewed pages/images, etc. Firefox has internal features to clear these either on demand or at shutdown. For more information, see:

Delete browsing, search and download history on Firefox
