Many users maintain multiple accounts on various websites, for example two Gmail accounts one for business and one for private contacts or multiple Facebook or MySpace accounts. Using multiple accounts is usually privacy related but it could also be used for other purposes. The main problem that most web browsers have with multiple accounts on the same domain is that they cannot maintain more than one cookie for that site.
If a user logs into the first account, opens a new tab and logs into the second the cookie for the first account will be overwritten by the cookie for the second account effectively logging off the user account in the first tab.
Google Chrome is the only browser that supports - most likely unintentionally - simultaneous account usage. Users can make use of the so called Incognito Mode which makes use of its own cookie storage. Incognito Mode is a privacy mode that deletes any traces of the session after closing it.
Google Chrome's Incognito Mode can be used to login twice into any web service. The user would login normally at first and press [CTRL Shift N] afterwards which would open a new browser window in Incognito Mode. The new browser window could then be used to log into the service a second time.
Firefox users can install the Firefox add-on Cookie Pie which maintains separate cookie storages in tabs and windows if activated. It basically has the same effect that the Incognito Mode of Google Chrome has with the difference that the browsing history will not be deleted after closing the session.
Opera users who want to use Opera and nothing but could make use of different profiles to achieve the same results although it would probably be easier to start a second browser and use this for the second login. There is a Gmail Widget for Opera that provides access to two Gmail accounts.
Does anyone know how Internet Explorer 8 and Safari handle that issue?
