Log in with two accounts (e.g., in Gmail) in a single Firefox window

Question

I have two Gmail accounts.

I'd like to log in to both of them at the same time in a single Firefox window.

How would I go about it?

I know one suggestion is IETab, but that fix has too much of a duct tape feel to it.

There are some other questions covering this, but not necessarily within the same Firefox window:

• Firefox: Using multiple instances with different profiles?
• How to open multiple firefox windows with distinct sessions? [closed]

Answer 1

Gmail now supports using multiple accounts simultaneously on the same browser.

Answer 2

Also, if you are just checking mail. You can use one gmail account to check the mail of another http://mail.google.com/support/bin/answer.py?hl=en&answer=21288

Answer 3

Mashable has "5 Ways To Log Into Several Gmail Accounts At The Same Time":

1. Multiple browsers
2. Master account to which you forward all other accounts
3. IE Tab (Windows only; basically an additional browser within one window)
4. Gmail Manager
5. Google Account Multi-Login (Greasemonkey script)

For Internet Explorer 8 users :

start Internet Explorer with -NOMERGE argument

iexplore.exe -nomerge

then each instance started will run in a isolated session environment so you can open another Gmail account or any other web service.

Answer 4

To my knowledge, this can't be done well and only works in IETab because the IE engine is embedded into a firefox tab.

One option is to install Prism, an official firefox extension and run one or both instances of GMail as an 'application'. This doesn't work in a single window but is a nice solution, and gives you a faster (no addons) window for your GMail to run in.

Answer 5

As Revolter mentioned Google Account Multi-Login greasemonkey script can allow you to login into multiple accounts.

Answer 6

http://webmailnotifier.mozdev.org/ - it will check any number of different types of email accounts. You can open the relevant webmail page from a link in the plugin's menu, sidebar, icon.
