Amazon Container is a browser extension for the Mozilla Firefox web browser to isolates Amazon activity from the rest of your browsing activity.

The add-on is a fork of the Google Container extension which itself is a fork of Mozilla's own Facebook Container extension.

Mozilla introduced the Container feature as an experiment back in 2016. It enabled users of Firefox to separate activity into containers under a single user profile. A container stores certain data, such as cookies or local storage, separately from the rest of the browser. Containers limit tracking first and foremost, but they are also useful when it comes to signing in to the same service with multiple accounts among other things.

Containers never made it natively into Firefox but Mozilla published the Multi-Account Container extension

Amazon Container for Firefox

Amazon Container is one of several company or site specific container extensions. It works as standalone extension but better if you have installed the Multi-Account Container extension as well.

Note that you will be signed out of Amazon when you install the extension. Some Amazon specific features that are available on third-party sites may not work properly when you install the extension. Amazon embeds, e.g. likes or comments, won't function; the same is true for services that let you sign in with an Amazon account.
