How to clean \cache2\entries in Firefox?

Hi there,

with new version of Firefox I have noticed that CCleaner can clean only few megabyte, something about 13/15 each time I use it, but I have discovered that in "C:\Documents and Settings\culo\Impostazioni locali\Dati applicazioni\Mozilla\Firefox\Profiles\e4rgm794.default\cache2\entries" are stores so many megabyte that my free version (4.01.4093) of CCleaner doesn't wipe out.

Is there any way to make CCleaner can clean all these files?

Thank

free version (4.01.4093) of CCleaner

That's an old version of CCleaner! Try updating from here to see if the newest version cleans more.
