AWS Console Containers stores your IAM Identity Center configuration (start URL, region), discovered account/role profiles, and short-lived AWS SSO tokens in Firefox's extension storage on your device. This data is transmitted exclusively to Amazon Web Services endpoints (oidc..amazonaws.com, portal.sso..amazonaws.com, signin.aws.amazon.com) to perform the sign-in and console-opening actions you explicitly invoke. No data is collected by, transmitted to, or shared with the developer or any third party. Removing the extension deletes all stored data.
