There are many instances where logging on to multiple Facebook accounts becomes a necessity. Say for example, you have an official Facebook account that you use for work, along with your own personal account. Usually, what people do is log in and out between these accounts, or use two separate browsers (Chrome and Firefox).
But what if you need to access more than two Facebook accounts at once? Even using two Facebook accounts at once can be quite a messy situation. But thankfully, there’s a handy little Chrome extension called ‘Identity Mask’ that lets you run multiple accounts (on Facebook, Twitter, G+ and the like) without having to sign-in/sign out or use different browsers.
