Features & Capabilities

VulnRadar scans the page you're looking at without pasting a URL into anything. Click the toolbar icon, hit Scan, and get results from the same 700+ check engine as the vulnradar.dev web app: security headers, TLS and certificate issues, cookies, DNS and email records, exposed secrets, information disclosure, and more.

Connect your VulnRadar account with an API key (free tier available) and the extension becomes a thin client over your own scan history, nothing is stored separately. Quick and Deep modes mirror the web app's scan form. An optional on-page card can flag a host you've already scanned, or that hasn't been checked yet. Auto-scan modes (on page load, on tab focus, on URL change) are available but off by default.

The extension reads the current page's URL to run a scan and to check known-result status. It does not read page content, and nothing is sent anywhere except vulnradar.dev's own API.

Is VulnRadar Website Scanner 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.

VulnRadar Website Scanner 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.

VulnRadar Website Scanner is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
