Features & Capabilities

Safe CORS lets developers bypass CORS restrictions on a per-tab basis, controlled entirely from page scripts. Unlike traditional CORS extensions that use a toolbar toggle to disable CORS globally, Safe CORS is activated programmatically from your own code — making it ideal for local development and testing. HOW TO USE Open your browser console (F12) and run: // Enable CORS bypass for this tab document.dispatchEvent(new CustomEvent('CORS_DISABLE_TOGGLE', { detail: { enabled: true } })) // Disable CORS bypass for this tab document.dispatchEvent(new CustomEvent('CORS_DISABLE_TOGGLE', { detail: { enabled: false } })) Or add a helper to your development page: function setCors(enabled) { document.dispatchEvent(new CustomEvent('CORS_DISABLE_TOGGLE', { detail: { enabled } })) } if (location.hostname === 'localhost') { setCors(true) } WHY "SAFE"? • Per-tab only — other tabs are unaffected • Session-only — close the tab or restart the browser and it's gone • Page-initiated — no accidental global CORS bypass • No data collection — the extension collects nothing

Is Safe CORS Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Safe CORS requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Safe CORS may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
