AWS Signer Browser is a Firefox add-on that automatically signs requests to Amazon Web Services (AWS) using your access key and secret according to the Signature Version 4 signing process. It can handle multiple services and hosts and is especially helpful when accessing front-ends of services in AWS like Kibana and S3.
