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.
