We tend to have many Google Accounts and associate them with all the great free services provided by Google. But it may become quite a cumbersome task to log out and log into each and every Google account to check email or may be to share different items on Google Reader through your different Google Talk accounts. In this article we will show you how to switch between multiple Google Accounts. This trick is supported on all major Operating Systems that run Firefox Browser. 1. Install the GreaseMonkey Add-on for firefox and restart your firefox browser.
2. Now, Install the Google Account Multi-Login script for GreaseMonkey. Make sure that GreaseMonkey add-on, you just installed, is enabled. Without this, the script won't work. To confirm that the GreaseMonkey add-on is enabled just check whether the monkey icon in the Firefox status bar is in colour. If it is grayed out then GreaseMonkey is disabled. Just click on that icon to enable GreaseMonkey. Check these screenshots:
