How to Use Multi-Account Containers in Firefox


Multi-Account Containers is an add-on launched by Firefox designed to help you reduce your digital footprint. It uses “containers” so you can separate your browsing activity for multiple profiles on your computer, which helps you manage your browser's cookies.

In this guide, we'll show you how to use the Multi-Account Containers add-on, so you can make the most out of its features.

What Firefox Multi-Account Containers Can Do for You

First and foremost, the extension separates your browsing activity. If you use the same Firefox account both for work and personal browsing, you can keep these two separated. For example, you can hide your work-related container once you get home or when your shift is over.

The add-on also allows you to log in to different accounts on the same website without having to use private windows or different browsers. For example, if you have a personal email account and a work email account, you can open them at the same time using different containers.

Multi-Account Containers prevents tracking activity without logging out of websites while you browse. If you open a website in a container, it can’t track your browsing activity while using another container.

When using the add-on, it will open a website within the same container every time. This will stop any browsing mistakes such as visiting an online shop in your finance-related container. It can also help you avoid security attacks, by restricting any harmful activity to its container.
