Firefox starts after every boot [SOLVED]

[tomillares]

After boot firefox always opens. I've searched at menu/settings/sesion and at menu/sistem/services. Firefox isn't set to start at boot or to work like a service. I don't know what to do. It isn't serious. I only have to close firefox after every boot.
I don't why it started to happen. Can you help my to solve this issue?

I use LMDE xfce in a samsung n150 Plus netbook. Thanks.

SOLVED: Close firefox (and every program). Go to "Exit". Mark "save session...". In the next boot firefox doesn't start. I saved a sesion with firefox opend, and then I unmarked "save session".
