I cannot find any option either to stop CCleaner wiping the browsing history for Firefox or to be able to choose whether to wipe when closing Firefox. If I close Firefox and then open it again the history is still there, but if I start another program such as Word and then start Firefox, the history is empty. I have set Firefox to remember history. When I shut CCleaner down, the history is not wiped in this way, so CCleaner must be doing the wiping. I have set Firefox cache folders with path names too long to quote here to be excluded, but this is ineffective.
I would be grateful for advice on this. If CCleaner has no option to stop wiping Firefox, can I stop it being booted when the computer starts up?
