I am forwarding a domain (Domain 1) to a page within a website (Domain 2). It works on other browsers but not Firefox. I have done this successfully before, forwarding a domain (Domain 3) to a different page with the website (Domain 2). I have tried clearing cache/cookies, refreshing Firefox, uninstalling and reinstalling Firefox, using incognito mode on Firefox. Nothing works. Why does the page load successfully in other browsers, but not Firefox?
