Allow CSP is a free Chrome extension developed by Muyor. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools program. The main purpose of this extension is to easily remove existing Content-Security-Policy (CSP) rules from the response header.

This extension is particularly useful for web or mobile app developers who need to temporarily disable CSP rules. By opening the toolbar popup and clicking on the toggle button on the left side, users can activate the addon. Upon installation, the default state of the addon is inactive, indicated by a grey icon color. Once activated, the toolbar icon turns blue. Users can manage the whitelist table by adding or removing the active tab domain via the toolbar popup.
