I am unable to store a cookie for a site on Firefox 16.01 for windows. It always logs me out and i have to log in. I have repeatedly changed the settings to allow cookies but for some reason, it does not stores cookies for this site. Usually, I was logged in until I logged out. It's not really a very important site and so far, this has not surfaced with any other sites that have logins, except for banks etc, which log you out.
