Problem with History deletion

I've used CCleaner for ages, and love it. But recently when I use the program it erases my Firefox history, even though I don't have "history" checked.

Can you please advise? I'm not sure what has changed with the program, but I will avoid using it if I can't fix this...

Thanks so much for any help you can offer!

do you have mozilla-sessions checked? try unchecking that and seeing if the problem resolves then report back
