In our application getting the CORS issue when running the application.I have tried installing the CORS add-on .That didn't work. In the older firefox version it is working fine there . Please resolve this if anyone has solution for this.

The error coming---- Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://"url" (Reason: CORS request did not succeed).

Sounds like a addon issue not related to firefox browser. If the addon is out of date and doesn't pass the newer security checks it will not work.

Previous version it was working fine without the add-on .But in this version i am facing issue

hi, Cross-Origin Resource Sharing (CORS) policies is something that your web server is specifying and predetermining. firefox 65 has become more standards-compliant in this area: https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/65#Security if something is breaking now, you'll have to adapt the server-side rules...

https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

In the response we are getting the status as 0 and readystate as 4 ?

It is working in all other browser and also i have set the values as defined in this article for CORS .
