List all my buckets when account assigned - if checked, S3 Browser performs s3:ListAllMyBuckets call when account is assigned. You may uncheck this for accounts that are not allowed to list all buckets to avoid failed tasks and warnings in the log.

Check CloudFront distributions when account assigned - if checked, S3 Browser performs cloudfront:ListDistributions call when account is assigned to set special icon for buckets that are used as origin for CloudFront distributions. You may uncheck this for accounts that are not allowed to list CloudFront distributions to avoid failed tasks and warnings in the log.

External Buckets - you may edit external buckets associated with the account. Each bucket must be specified on a new line. Optional path is also supported, slash is used as delimiter, for example my-bucket/and/optional/path
