Good news for Gmail users, Internet Explorer 8 lets you to access multiple Gmail accounts. It provide users to access multiple Gmail accounts simultaneously and independently.
This is accomplished via the New Session option, which makes it possible to log onto Web sites that track your identity across different tabs–like Gmail.
If you use Firefox, for instance, you can’t access multiple Gmail accounts open in multiple tabs or Windows. If you sign into a second one, you’ll get signed out of the first one when you try to do anything or If you sign in and you want to sign in with different account in new tab you can’t do this.
Though IE8 has removed this hurdle by adding New Session feature.
Here’s how to utilize this IE8 feature:
1. Open Internet Explorer 8 and login to your Gmail account. Make sure the Remember Me option is unchecked when you sign in.
2. Press Alt-F, I, and then hit Enter. This will open a new Internet Explorer session (which for all intents and purposes is the same as a new IE window).
3. Open Gmail and sign in with different account, again making sure to uncheck Remember Me.
You are done now!
Conclusion: In my opinion if you prefer Gmail to remember your username and password from one session to the next then Firefox is best for you, otherwise IE8 is the best alternative for whom want to use two different Gmail account simultaneously.
