Firefox extension CookiePie manages Firefox’s cookies—small bits of text stored on your computer that tell a site you’re logged in, for example—in such a way that you can log into the same site multiple times.

How to use it?

Just follow the steps given below:

• Install CookiePie Firefox Extension.
• Create a new tab or use an existing one.
• Open the context menu of the tab (i.e: Press the right mouse button over the tab) and select “Toggle On/Off CookiePie”.
• A cookiepie icon will appear over the tab.
• Go to a site (e.g.: http://www.gmail.com) and login into your account.
• Create another tab.
• Enable CookiePie on that tab too.
• Log in with another account on the same site.
