Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension helps you to retrofit a strict Content Security Policy (CSP) header to the current web page by analyzing its' contents.

This is especially useful for older web pages that do not yet implement a strict CSP.

Note: The CSP is a best guess based on the current page. Support for font sources and connect sources is still being worked on!

The extension is built upon AutoCSP that was first developed by Ferran Basora in 2016.
