What does "ERR_BLOCKED_BY_ORB" mean?
"ERR_BLOCKED_BY_ORB" is a browser error indicating that a requested resource was blocked because it violated a security policy related to its origin. Although the exact meaning can depend on context, here’s the general idea: • What It Means: – The “ORB” part of the error is shorthand for an origin-based blocker. In effect, the browser’s security system (which enforces same-origin and other related policies) has determined that the resource or request does not meet the necessary criteria to be safely loaded. – This is often related to cross-origin restrictions. For example, if your page (origin A) is trying to fetch a resource from a different domain (origin B) and that resource isn’t set up (via CORS or other header-based policies) to allow such requests, the browser will block it. • Common Causes: – Missing or incorrect CORS (Cross-Origin Resource Sharing) headers on the server hosting the resource. – Server responses that do not include proper Cross-Origin Resource Policy (CORP), Cross-Origin-Opener Policy (COOP), or Content-Security-Policy (CSP) headers, thereby causing the browser to deem the request as a security risk. – A configuration in a browser extension or a custom security feature that further locks down cross-site requests. • How to Address It: – If you control the server hosting the resource, check that you are sending the correct CORS headers that allow access from the origin making the request. – Ensure that any cross-origin policy headers (like CORP or CSP) are correctly configured so that legitimate requests aren’t unintentionally blocked. – If the error is coming from a third-party resource, you might need to consult that service’s documentation or support to see if they have updated their security policies. In short, "ERR_BLOCKED_BY_ORB" is the browser’s way of telling you that it has prevented an action (such as fetching a resource) because it would have broken its rules about how origins can interact.

"ERR_BLOCKED_BY_ORB" is a browser error that indicates a resource request was blocked due to security rules based on the request’s origin. In other words, the browser’s origin‐based resource blocking mechanism (sometimes referred to as ORB) prevented the resource from loading because it didn’t meet the security requirements for cross-origin requests. Here’s what that generally means: • When a webpage makes a request (for example, for an image, script, or data) from a different origin (domain, protocol, or port) than the webpage itself, the browser applies security policies to guard against potential cross-site data leaks or other vulnerabilities. • If the requested resource doesn’t provide the expected security headers (such as appropriate CORS, CORP, or related headers) or if its origin doesn’t match the expected one, the browser can block the request. The error code "ERR_BLOCKED_BY_ORB" is a signal from the browser that this kind of origin-based blocking has occurred. • Although you might see similar errors like "ERR_BLOCKED_BY_CLIENT" (often due to an extension like an ad blocker) or errors related to Cross-Origin Read Blocking (CORB), "ERR_BLOCKED_BY_ORB" specifically points to the browser’s internal mechanism that enforces origin-based restrictions. If you’re a developer encountering this error, you might consider: – Checking the response headers of the resource to ensure they meet your site’s security policies. – Verifying that CORS or other cross-origin policies are correctly set up on the server hosting the resource. – Reviewing any recent changes in browser security policies that might affect how resources are loaded between different origins. For users encountering this error on a website, it means the browser has intentionally blocked a resource to protect you, and it’s an issue for the website’s developers to address.
