The Disable Content-Security-Policy Chrome extension allows developers and testers to disable the Content-Security-Policy header on individual browser tabs. This functionality is essential for web application testing, particularly when examining what resources third-party tags inject onto a page. When the extension icon is colored, it indicates that CSP headers are currently disabled for that tab, allowing for convenient toggling by clicking the icon.

This tool should be used cautiously and only as a last resort since disabling CSP removes crucial protections against cross-site scripting attacks. It's recommended to use CSP reporting features like report-uri.com, which enable monitoring of CSP violations without disabling the policy entirely. This makes the extension a useful utility for developers performing in-depth analysis and testing of web security policies and resource loading behavior.

Extension safety

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.

Disable Content-Security-Policy requires a few sensitive permissions. Exercise caution before installing.
