Details
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0 Steps to reproduce: 1. Goto www.test-cors.org/#?server_enable=false&server_tabs=local 2. Open DevTools 3. Select network tab 4. Click [Send Request] Actual results: Network tab shows a successful request, status 200. Console shows this warning: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://server.test-cors.org/server?id=2047290&enable=false&status=200&credentials=false. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Expected results: The new request should have some marker indicating that the request was blocked. Here's why: I had a situation where my JavaScript raised a network error but the network tab showed all green. That lead me to think that my error handling was wrongly triggered. A colleague had the idea that it might be a CORS issue. To verify that, I had to look at console warnings. Warnings are usually not displayed because minified code often shows a lot of those, drowning out the important errors. Therefore, I hadn't seen anything in the console.
