Firefox with AWS API Gateway returning a 307 redirection is not working. The API gateway is configured to use Cognito and so the GET request HTTP header is set with "Authorization" and all the servers both AWS and the redirection server is configured to return response with Access-Control-Allow-Origin: * Firefox is not showing the redirection URL request in the web developer. Also tried in safe mode didn't worked there also. Same website works fine in Google chrome and the 307 is redirected to the one specified in the location header and the same Authorization header is both send to AWS and to the redirected URL.
