Script Summary: Automatically logins in to MySpace if Firefox remembers your password. Works with new MySpace changes unlike all the others.
I know that there's tons of these, but this one actually works and will be updated as the MySpace site changes. Please keep me informed of any bugs as I will be checking this periodically.
I have incorporated this script into another one of my scripts: MySpace Simple Login Screen w/Auto-Login. Check that out if you wish.
