How can I reset my browser setting?

How can in reset my browser setting for e mail automatic opening?

• Answer:

  I notice when I hit the "X" to sign out instead of hitting "SIGN OUT" in my email FIRST, it will open right back up to my email account just by clicking on the email icon on my desktop. Always hit "SIGN OUT" when leaving your email accounts. Any account actually. Like yahoo messenger, my yahoo, etc. Otherwise whoever sits down at your computer after you can gain access to your accounts just by opening the icon. You can also check to be sure you're signed out by clicking on the email icon to see if it asks for a login or if you're still signed in. Hope this helps...
