somehow similar problem here: ccleaner won't show and won't delete any internet cache files of firefox when not using the standard path (see Browser.cache.disk.parent_directory) after a reboot.
not working in ccleaner 2.19.901, 2.23.993 and 2.23.999.
not on win xp, not on vista.
i'm using firefox 3.0.1x.
reinstalling firefox or ccleaner didn't help.
everything's patched and up to date.
any suggestions?
