I have just downloaded the latest version of ccleaner and there does not seem 2 b any capacity 4 cleaning the Safari browser.
Safari cleaning has been in CCleaner for some time now, unless of course you may have installed it into a custom location perhaps that can make the cleaning not work.
Change log:
Cleaner v2.17.853 (Released February 27, 2009):
* Improved Apple Safari history cleaning.
