I am using Chrome and gmail  mail box on window 7 computer.
Since I have three email accounts at gmail.com. Could I open all email account  together
on the same Chrome browser with difference instances ?
I tried it, but all three instances within the same browser will show the
last email account I login after I login three different email account individually.  Why ?
Other browers can do that such as FF or IE ?

Please advise

You could also try and use the incognito tabs. However I'm not sure if that still works.

The problem is that web sites use cookies to tell what you are logged into.  And the problem with that is that all open windows of a browser see the same cookies.  So when you login to another account for the same site, the cookie for the login is changed to the new account and that's what all the open windows will see now.  To login to separate accounts on the same website, you have to use different browsers to login to each account so the cookies don't get overwritten.
