S3 Bucket Scanner от Jsmon

The S3 Bucket Scanner is a lightweight Firefox extension that automatically scans web pages, JavaScript files, and website source code for exposed Amazon S3 bucket URLs while you browse. It categorizes detected buckets into three types:
- 403 (Access Denied) – Bucket exists but is restricted.
- 404 (No Such Bucket) – Bucket does not exist.
- Public (Listing Enabled) – Openly accessible bucket.

The extension provides a simple popup UI where you can view, filter, and export all detected S3 bucket data for further analysis.
