Clicking Settings shows you your username, account expiration date and credit balances. You can also see or change your default firewall and time zone settings.

The default firewall and time zone settings are specific to the browser and are stored in a browser cookie. If you change browsers or computers this value may change, most often to a default setting or the setting you last had for that browser on that computer system. For example, you might perform labs at work with a firewall setting of "Tarantella," but then log in at home and discover your default firewall mode is now "Standard". You may keep it "Standard" at home, then return to work to find your setting is again "Tarantella." These settings will also change back to default settings if you delete all the cookies within your browser.
