Virtual Kiosk And Firefox

I would like to use Virtual Kiosk mainly to avoid drive by viruses. When I clean the kiosk time to time, is there any way to retain browser history, cookies and other data and make it remain after cleaning the kiosk?

It would be removed as well. However, if you like you can add the files containing the history, cookies, etc… to your list of files to exclude from sandboxing. This will slightly decrease your security, but it would also allow the relevant data to be persistent.
