When I click “Contribute” button on any addon page and then “Make contribution”, connection to PayPal times out and error page appears.
Is seems that addons.mozilla.org is trying to connect to urls like this: https://paypal.com/webapps/adaptivepayment/flow/pay?paykey=xxx which are not responding. When I add “www”: https://www.paypal.com/webapps/adaptivepayment/flow/pay?paykey=xxx and manually visit this url page loads without any problem.
Could you confirm this problem or does this issue only occur in my network?
