that's ok for the cache but I think it seems a bit difficult for other files like cookies.txt or the history that I do not want to delete, but just want to clean... And I don't know what are the other files that Ctrl+Shift+Del usually cleans...

Hi. CCleaner usually cleans Firefox files from C:\Users\XXX\AppData\Roaming\Mozilla\Firefox\Profiles. But if you decide to move this folder onto another partition of your hard drive using the profilemanager of Firefox (execute: firefox.exe --profilemanager) in order to access your profile from several OS (eg vista, xp and unix), this folder is no longer cleaned... until you do it yourself with Firefox. It could be a good idea to look at the C:\Users\XXX\AppData\Roaming\Mozilla\Firefox\Profiles.ini file which contains the new profile location before cleaning thanks!
