I have my privacy settings to clear cookies and history when I close Firefox. I closed Firefox. When I reopened, the cookies were still there. So I manually cleared them (Remove all). Gone. Then I closed and reopened settings and clicked Show cookies. The ones I just cleared were all back again. I can't get rid of these things. What do I do?
