Description from store

CSP Evaluator is a small tool that allows developers and security experts to check if a Content Security Policy (CSP) serves as a strong mitigation against cross-site scripting attacks. Reviewing CSP policies is usually a very manual process and most developers are not aware of CSP bypasses.
CSP Evaluator checks are based on a large-scale empirical study and are aimed to help developers to harden their CSP. This tool is provided only for the convenience of developers and Google provides no guarantees or warranties for this tool.

In every page i tried it it said: "No Content Security Policy found". And yes, these pages had CSP configured.

This extension stopped working for me in the past couple months in the Brave browser. I recently disabled, removed, and reinstalled and it's working again. For those who are having trouble with it working, give the reinstall a try.

I have a CSP but this doesn't detect it. So disappointed.

It doesn't detect meta CSP and it doesn't say anything about it on the description

For some unknown reason, when the extension was enabled, my browser sent additional requests to the sites. As a result, I lost a lot of hours debugging my site and trying to find the cause of the duplicate requests. As soon as I turned off the extension, the problem disappeared.

Macht wenig überraschend exakt das was dran steht. Keine Ahnung was an anderer Stelle schief gegangen ist, aber es funktioniert sogar in Edge.

liked it. saved me some headaches!!! was playing around for weeks to get my csp right! there's one drawback though. after copying it all to my policy file it bricked my wordpress login page. so i had to revert back using ftp access to my server to find the problem..... again.

It doesn't detect meta CSPs which should have been stated in the extension details.

cool. May be better if it's possible to add/remove CSP directives so I can test without deploying codes lol

Where to post the issues? It shows 'Directive "prefetch-src" is not a known CSP directive.', https://w3c.github.io/webappsec-csp/#directive-prefetch-src

It appears that the extension does not consider CSP in meta tags.
