CSP Unblock Extension

This extension removes the following CSP-related response headers to remove limitations caused by CSP.

1. \"content-security-policy\" header
2. \"content-security-policy-report-only\" header
3. \"x-webkit-csp\" header
4. \"x-content-security-policy\" header

Use Cases:
1. This extension can temporarily remove the limitations of CSP so that the developer can test inline and remote scripts. Also, you can load different cross-origin resources without any limitation.
2. Allow a website to load a remote worker script
3. Allow a website to play remote media

Notes:
1. Disable the extension when you are browsing the internet. By removing CSP, the website's protection reduces significantly which might harm you.
2. The extension removes specified CSP-related headers from the top-frame and all sub-frame elements

Definitions:
\"content-security-policy\" header: The HTTP Content-Security-Policy response header allows website administrators to control resources the user agent is allowed to load for a given page. With a few exceptions, policies mostly involve specifying server origins and script endpoints. This helps guard against cross-site scripting attacks (Cross-site_scripting).

\"content-security-policy-report-only\" header: The HTTP Content-Security-Policy-Report-Only response header allows web developers to experiment with policies by monitoring (but not enforcing) their effects. These violation reports consist of JSON documents sent via an HTTP POST request to the specified URI.
