Features & Capabilities

The extension aims at helping ethical hackers to check easily and quickly if a website publishes a security.txt file (cf. RFC 9116 A File Format to Aid in Security Vulnerability Disclosure). It does so by:

showing a red (no such file) or green icon (file present);
displaying its content. Caveat: When a [root directory]/.well-known/security.txt file exists, its content is displayed without any syntax check.

Note to people intending to get in touch with me to “help my extension grow”, “drive growth for Firefox extensions”,...: don't waste your time, I definitely do not want to waste mine. This extension is, and will remain FREE.

Is security.txt file detector 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.

security.txt file detector 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.

security.txt file detector is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
