Firefox keeps signing me out when restarting computer

Every time I restart my computer I get logged out of my Firefox account. This does not happen when I close the browser only when I shutdown or restart my computer. I have tried removing add-ons and also making sure the browser remembers cookies when it closes. Is there a way so Firefox won't log me out and have to sign into sync after a computer restart?
