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.

- Restart your Firefox.
- Go to mail.com and login to your email inbox

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.
