Chrome Cookie Switcher

Cookie Switcher allows you to save cookies for a website to a profile, then easily switch between your saved cookie profiles.

The main use case is switching between multiple accounts on a particular website — for example you may want to frequently change between personal and work Twitter accounts. Cookie Switcher allows you do to this without having to log in each time. It was originally developed to allow websites to be tested quickly with multiple user accounts.
