I'm new to TOR. I downloaded TOR Bundle for Mac OS. My current version is 10.12.6. When I launch TOR it looks like Firefox but shows TOR Browser in the top line of the tab (menu line?). I have an American Express account and I can access it using Safari or Firefox. The URL I use to access my American Express account rejects me by saying: "You don't have permission to access "http://online.americanexpress.com/myca/logon/us/action/LogLogonHandler?" on this server. Reference #18.17dcf180.1505760563.19f6a98." I'm not sure why the error message does not show https and only http. The URL shows a secure https. What setting do I need to change to allow access? I need an answer suitable for a kindergartener. Thanks.
