How to Open Multiple Facebook Accounts Simultaneously in One Browser

Ever wondered how to open a Facebook account on your desktop or notebook computer? Maybe you think like I think, is to use several different types of browsers.

That way would probably be able to resolve the problem before, but there is a way if we want to open a Facebook account just by using a browser alone.
The way is:

• Install the add-on for Firefox. Its name is CookiePie 1.0.5 (Choco Torta). Go to the web page http://www.nektra.com/products/cookiepie-tab-firefox-extension then click on "Install Extension"

• If your browser application asks to continue the installation process, clicks allow. Wait a minute, there will be a screen appears to ask you to install. And select Install Now. If already installed, Firefox will ask for restart.

• To use the Toggle Cookies, right click on the tab you want to open as a "new facebook tab" then select "toggle on / off cookie".

Unfortunately we could only just opened three accounts with this add-on. But this is better than nothing. So you can open the game up more, so no need to sign in and sign out again. The advantage is this add-on can also be used to other websites too.
