The Firefox Containers feature is a privacy and security tool that helps users separate their online activities by creating isolated containers for different websites and web applications. It allows users to browse the web with multiple identities, segregating their online presence and preventing websites from tracking their activities across different containers.
Here's how it works:
- Containers: Firefox Containers function as virtual tabs, where each container is isolated from others. By default, there are four container types: Personal (default), Work, Banking, and Shopping. Additional containers can be created and customized as needed.
- Site Isolation: When a user visits a website within a specific container, Firefox ensures that all subsequent requests from that site are also loaded within the same container. This helps prevent tracking across different containers or websites.
- Cookie Isolation: Cookies are stored separately for each container. This means that a website cannot access cookies from another container, limiting cross-site tracking.
- Container Tabs: Users can open container tabs directly by right-clicking on links or using the "+" button beside the tab bar. This allows them to open specific websites in designated containers.
- Customization: Users can customize the behavior of specific websites within containers. For example, a user may choose to always open a particular website in the Shopping container.
The Firefox Containers feature strengthens user privacy by compartmentalizing online activities and reducing tracking across the web. It provides users with more control over their data and the ability to manage multiple online identities easily.
