Google’s email service Gmail is highly popular. One of the restrictions that many users face is that it only allows to sign into one account at a time in the web interface. That’s problematic if a user operates multiple accounts and needs to check them regularly. This is for example the case in companies that use more than one gmail email account. It is possible to use a desktop email client to retrieve all Gmail account messages at once. We recently reviewed a Greasemonkey script that would allow a user to manage multiple Gmail accounts (read: Gmail Login).
The Firefox add-on Gmail Manager is another possibility. It is a highly popular add-on that allows a user to manage multiple Gmail accounts at once. It places an icon in the Firefox status bar that provides quick access to all registered Gmail accounts. Options provided are information about the unread emails count of each Gmail account and the possibility to write emails using a specific account. Notifications can be configured to inform the user if new unread emails are available in one of the accounts and tooltips are available for additional information and mail previews.
Gmail Manager supports Gmail hosted accounts and provides one click access to any Gmail account that has been added to the Firefox add-on.

The Firefox extension is an excellent companion for Firefox users who operate multiple Gmail accounts.

I have been using this for more than a year to manage my 3 gmail accounts. It is updated regularly, and always works well. I have it log in to my accounts automatically, and I get a pop-up whenever any of my accounts gets a new email.
It works well combined with Google Account Multi-Login, which is a GreaseMonkey script that somehow juggles your cookies and lets you stay logged in to multiple gmail accounts simultaneously. It also replaces the “log out” link with a drop-down box that lets you change accounts easily. With this, I can keep my work email open while adding events to my personal Google Calendar. It’s fantastic!
Just a heads up, I’ve noticed this addon has trouble with Google Offline (Gears) as it always shows 0 new emails. There are others on their support forum with the same issue. Otherwise, it’s great and highly recommended.
i know it’s not an option for some, and for others they’d rather access email via the browser, but personally, i’d say this is another reason for setting up POP3/IMAP access in an email client like Thunderbird. i also like the fact that my Google account isn’t logged in at all times because i’m using the web interface.

You can also do this by simulating multiple sessions using multiple profiles.
