CSP Unblock is a free Chrome extension developed by balvin.perrie. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This extension is designed to remove all Content-Security-Policy (CSP) related headers during website testing.

With CSP Unblock, developers can temporarily remove the limitations imposed by CSP in order to test inline and remote scripts. It allows for the loading of cross-origin resources without any restrictions. Additionally, the extension enables websites to load remote worker scripts and play remote media.

It is important to note that the extension should be disabled while browsing the internet. By removing CSP, the website's protection is significantly reduced, which may pose a risk to the user. The extension removes specified CSP-related headers from the top-frame and all sub-frame elements.

In summary, CSP Unblock is a useful tool for developers looking to bypass CSP limitations during website testing. However, caution should be exercised when using this extension to ensure the security of browsing activities.
