Overview

Product summary

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

Allow CORS: Access-Control-Allow-Origin lets you easily perform cross-domain Ajax requests in web applications.

Simply activate the add-on and perform the request. CORS or Cross-Origin Resource Sharing is blocked in modern browsers by default (in JavaScript APIs). Installing this add-on will allow you to unblock this feature. Please note that, when the add-on is added to your browser, it is inactive by default (toolbar icon is grey C letter). If you want to activate the add-on, please open the toolbar popup and press the toggle button on the left side. The icon will turn to an orange C letter.

If you have a feature request or found a bug to report, please fill out the bug report form on the add-on's homepage (https://mybrowseraddon.com/access-control-allow-origin.html).

Bypass CORS (Cross-Origin Resource Sharing) restrictions by injecting permissive Access-Control-Allow-Origin and related headers into HTTP responses

Modern browsers block cross-origin Ajax requests by default for security. This extension removes those restrictions during development/testing so developers can make cross-domain API calls without running into CORS errors.

User installs extension, clicks toolbar icon to toggle CORS bypass ON (icon turns orange). All HTTP responses now include permissive CORS headers. User can whitelist specific domains, configure header values in the options page, or add custom per-domain rules. A test page and YouTube tutorial are linked from the popup.

Target users: Web developers debugging cross-origin API requests during development / Frontend developers testing applications that consume APIs from different origins

Verified contents JWT hash in _metadata/verified_contents.json triggered false-positive 'jwt' keyword but is not auth-related
No external service dependencies; extension operates entirely within the browser using declarativeNetRequest API

Monetization

No paid features detected

No paid features, premium tiers, subscription gates, or payment integrations exist. The extension is entirely free. A voluntary 'donation' button in the popup links to the developer homepage with a support parameter — this is not a feature gate. No Stripe, no license keys, no upgrade prompts, no billing API calls.

Confidence: 97
Payment platform: --
Source: AI / High
Login required: No
Reason: No login, authentication, or account system exists in the extension. All 'session' keyword hits refer to Chrome's chrome.storage.session API for managing browser-level declarativeNetRequest session rules — not user authentication sessions. No login UI, no auth tokens, no credentials flow found in any source file.
