Firefox Containers

Firefox Containers let you categorize your browsing activity and compartmentalize cookies and other browser storage. Essentially, they stop websites from tracking your web browsing, preventing them from seeking anything outside their own container and following you around. It's a great alternative to deleting your cookies and cache, or refusing cookies, which can break some websites or cause them to not work properly.

How to Install Firefox Containers

Containers are an add-on for Firefox. You can install them like any other.

  1.  Open Firefox, and head over to the Containers add-on page.  Select Add to Firefox to download the add-on.
