Features & Capabilities

S3BucketList automatically monitors your browser's network requests to discover Amazon S3 bucket URLs as you browse. Designed for penetration testers, security researchers, and bug bounty hunters, it filters noisy results, instantly notifies you of finds, and aggregates any permissions or access patterns it can extract from discovered buckets.

Save time and reduce manual searching: S3BucketList runs in the background, highlights valid S3 endpoints, and presents a concise list of bucket URLs with extracted metadata. Lightweight and privacy-conscious, it helps streamline asset discovery and cloud security assessments without interrupting your workflow.

Is S3BucketList Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

S3BucketList requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
