There are many reason when you need multiple accounts at the same time. Suppose you use Google’s different products with different Gmail IDs and you don’t want to Logout from the current one to Log-IN to another Gmail account. Or you want to manage your multiple Facebook IDs or Twitter Account at the same time. Every site detects and saves our cookies on their server so usually only one cookie is served to each individual- this is how Sign-In function works on every site. So usually you can’t login with multiple ids on the same site. But As a TechSpree Reader you should not just limit yourself like others. Come lets win this limitation together.

Bonus Tip for Multiple Gmail Account Users:

Multifox Addons

Do you have multiple Gmail Accounts? You use them differently for different purposes? Google recently has introduced Multiple Sign In feature.

You can use upto 10 different Gmail and other Google Product accounts like Youtube/Analytics/Webmaster etc. with a single browser simultaneously.

How to use Google Multiple Sign in Feature:

• Log on to the Google Account which you want to be the Administrator of multiple accounts
• In the top Right Corner , Click on your E-mail Account
• In the Drop Down menu Click Add Account
• After clicking Add Account a new tab will be opened where you can sign-in your additional Google account. Repeat this process and Add all of your Google accounts

All Account will be listed on the drop down menu shown above and you can Switch between those accounts very easily. If you sign-out from one account , all accounts will automatically be signed out. If you delete your cookie then you have to setup all accounts again- as Google uses cookies to store your all account informations.

Last but not the least- Use multiple account as much as you can. I prefer the first two methods which work very efficiently. Do you know another method which we missed here? Why not share with us?

After a FF upgrade (from maybe version 17 or 19 to version 22 I think, I'm a little late in complaining about this), the Multifox functionality stopped working. Now, when one tries to open a new identity profile (enabling multiple Yahoo or Gmail accounts to be open at the same time), there's an error message:

'Multifox is not available from private windows. Please try again from a regular window.'

Multifox Addon

I was previously able to 'privately browse' by turning off the history, etc., and this had no bearing on my ability to open a new identity profile window. Are there plans to restore this? I don't ever store history, but I'd like to see multiple e-mail accounts simultaneously. It's really a shame that this got 'fixed'.
