• Swap My Cookies - Chrome Web Store
  Swap My Cookies is a session manager, it manages your cookies, letting you login on any website with several different accounts. You can finally login into gmail, yahoo, hotmail, and just any website you use, with all your accounts; if you want to use another account just swap profile! It's a nice and working alternative to Google's "multiple sign-in", you can keep in memory all your profiles, and switch among them as needed; if you share your pc just swap the profile and you are done, instead of logging out from every account and logging in again! if you have multiple mail accounts use one profile per mail
