Installing Firefox Multi-Account Containers Add-on

Installing Firefox Multi-Account Containers Add-on improves your privacy and security by keeping your online lives, and the cookies that define them, separate from each other.

As you browse on the Internet, websites store cookies (small files) on your computer. When you visit a particular website again, it reads and updates the cookies it stored on your computer. While cookies occasionally may improve web surfing experience, they are also excessively used to track you.

Your web browser keeps all the cookies, from all the websites you visited, stored together.

Other than making it easier to invade your privacy and lower your computer security, cookies, hanging all together, create some practical problems.

For example, you may want to log into the same website with two different accounts. The way you would normally do this is with two web browsers. With one web browser you log into the website with your personal email, and with another web browser you log into the same website with your work email.

What if you have a third account you want to use? What if you want to log into multiple websites with both your personal and work email?

You eventually start to wonder:

  • How many different web browsers do I need?
  • How do I keep track of where I'm logged in, and with which web browser?
  • Do I use Firefox to log in as my personal or work email account?

This is not a sustainable solution. And you should not be forced to decrease your computer privacy and security by using other web browsers that are not Firefox.

Thankfully, installing Firefox Multi-Account Containers add-on addresses these challenges.

Installing Firefox Multi-Account Containers Add-on

Installing Firefox Multi-Account Containers add-on separates your online lives from each other. You can put each life into its own Firefox Container.

Firefox Container is a Firefox tab or a group of tabs. Each Container stores website cookies to its own, private, storage area. Cookies Firefox downloads into one Container are not available in other Containers.

Instead of running different web browsers, you can run different Firefox Containers in a single Firefox web browser.

In one Firefox Container (tab), you open a website and log in with your personal email. In another Firefox Container (tab that belongs to a different Container) you log in with your work email. From the website's point of view, you logged in from two different web browsers.

Each Firefox Container can have more than one tab. If you click on a web link and want to open it in a new tab, Firefox will open it in a tab that is in the same Container.

You can have a separate Container for everything you do: personal, work, social (one Container for each network), shopping, banks, news, and so on.

Keeping different types of web browsing separate from one another increases your Internet privacy and security. There are intrusive privacy violations going on all over the Internet. And serious security bugs are found in websites all the time. If different websites are kept in their own Containers, at least the security and privacy damage to your computer and personal data is limited.

We always practice defense in depth by inserting as many security layers between us and the danger as possible.

Tracking coming from social networks is a problem in itself. Social networks track you with no mercy. If you keep social network websites in their own Container (ideally each social network in a separate Container), at least when you read the news or go shopping they will not be able to track you. Well, at least not with cookies.
