Thanks for the prompt reply John. I've tried the 'Settings - Cookies' option but it's taking ages for 'Cookies on computer' list to fill; however, I'll percevere.
Sorry if this has been asked before but how do I preserve my preferences on sites like Google and Facebook. I'm not even sure this is a CCleaner issue but any advice would be welcome as I currently have to choose every time I visit/log into the sites.
