Can I create a new session in another tab or window in Google Chrome?
Currently, this is not possible.
You can use multiple profiles in Google Chrome, though. Read the instructions here.
- Enable multiple accounts: https://www.google.com/accounts/MultipleSessions
- Then, create a bookmark(let) or a keyboard shortcut for each mailbox:
https://mail.google.com/mail/u/0/#inbox
https://mail.google.com/mail/u/1/#inbox

MultiLogin is down from the google webstore, but there is an alternative (SessionBox) https://chrome.google.com/webstore/detail/sessionbox-beta/megbklhjamjbcafknkgmokldgolkdfig
