Hello, Would you like to stay logged in longer at mail.com? First, a quick note, that this is not recommended by mail.com, and some people would consider extending your login as weakening your account security. I started by checking the mail.com web page. You're right, there is no obvious "remember me" checkbox or a setting that can be used to extend your login session time. I checked the authentication cookie and it expires at the end of the session. Next we need a way to edit the cookie. I checked around for a Firefox plugin that supports the latest Firefox 7 and found this - Abine Install the plugin at the above link. Restart your Firefox. Go to mail.com and login to your email inbox While on your inbox page in your web browser go to Tools -> Edit Cookies -> Site's Privacy Info In the bottom right corner of the window scroll down to service.mail.com section and click the edit icon next to JSESSIONID : Click the radio button for new expiration date. I recommend not setting the date more than 30 days ahead. The easiest way to do this is to change the current month to the next month, for example changing Oct to Nov. After entering the new expires date for your JSESSIONID cookie click the save button. Bookmark your inbox. It should be a link like - Get free Email accounts: Web based and secure Email - mail.com Start a new Firefox. Go to your bookmarked mail.com inbox link so that you don't visit the actual mail.com home page. Unfortunately, mail.com goes out of it's way to prevent you from extending your login and you will be greeted with : I'll keep working on this and sticky it when there are working directions.
