Firefox error: The page is not redirecting properly (endless loop case)
When a webpage redirects you in an endless loop, Firefox will display an error with the message, The page isn't redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete. To solve this issue please try to delete all active redirects from your website (cPanel -> Redirects section) and make sure your index file does not have any active redirects as well. If it doesn't help, you may try to remove all entries from .htaccess file and then check if the problem was resolved.
