Features & Capabilities

Prompt Leak Guard helps AI users and developers check prompts, logs, and config snippets before sending them to AI chat tools.

It includes a popup scanner for pasted text and a supported-site warning script for ChatGPT, Claude, Gemini, and Perplexity. It checks for common API keys, service tokens, private key blocks, webhooks, signed URLs, credential-bearing database URLs, payment-card patterns, emails, phones, and dashed US SSNs. It can also generate sanitized text locally.

Privacy model: scanning runs locally in the browser. There is no backend scanner, analytics SDK, remote model call, or prompt upload.

Important limit: Prompt Leak Guard is a pattern-based safety check, not formal DLP. It cannot guarantee detection of every possible secret or private-data format. If a real key, token, password, or private key may have been exposed, rotate it immediately.

Is Prompt Leak Guard 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.

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

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. 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.

Prompt Leak Guard is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
