Full summary	Allow CORS: Access-Control-Allow-Origin is a handy Chrome extension that simplifies enabling cross-domain Ajax requests for web developers. By adding the header Access-Control-Allow-Origin: * to response headers, it lets you bypass the default CORS restrictions imposed by modern browsers on JavaScript APIs. Once installed, the extension remains inactive by default, indicated by a grey 'C' icon in the toolbar. Users can activate it via the toolbar popup, turning the icon orange, to start performing cross-origin requests seamlessly. It’s an essential tool for developers debugging or developing web applications that need to communicate with APIs hosted on different domains. For feedback or bug reporting, the extension provides a form on its homepage. Overall, it offers a simple toggle solution to a common web development challenge with CORS policies.	The Moesif Origin/CORS Changer & API Logger Chrome extension allows developers to bypass Cross-Origin Resource Sharing (CORS) errors by overriding request and response headers such as Origin and Access-Control-Allow-Origin. It supports modifying headers to permit cross-domain AJAX, XMLHttpRequest, and fetch calls directly from the browser. Additionally, the extension captures and logs API requests for debugging and analytics, sending data to your Moesif account. Features include real-time API monitoring, user behavior analytics, issue alerts, custom dashboards, and billing integrations. Designed primarily for development and testing, the tool includes domain whitelisting to limit usage and recommends disabling after debugging to avoid security issues. Moesif powers API observability for top companies, providing powerful insights into API usage and monetization.
