Hello, How can I enable CORS (Cross-Origin Resource Sharing) on Firefox so that I can access the data from a different domain than the one I'm currently on? I'm trying to fetch data from a website hosted on https://checkmepcobill.pk/mepco-bill-calculator/ , but it's showing me the 'Access-Control-Allow-Origin' error. Can anyone guide me through the steps to enable CORS on Firefox? Thank you in advance.

Open Firefox browser and in the address bar type about:config and hit Enter button. Click on I'll be careful, I promise! Button. In search box type origin. Look for security. fileuri. Double click on security. fileuri.
