Multiple Profiles Coming to Chrome [PICS]
Google is considering to implement a new feature in Google Chrome that would allow users to open different windows of Chrome and associate a profile with a specific set of browser windows, rather than with an entire running instance of Chrome. With multiple profiles, users can log in to different Google or Yahoo or any other service accounts using different Chrome windows.
Currently, if you log into your Google personal account from one browser window and wish to access your Work account, you need to log out from one account and then log in back again to another account. Multiple profiles would allows you to act as different users in different windows. The project in under development and with Multiple Profiles users can create a new profile and connect an unconnected window to a Google account.
