Filled out a form on a Japanese Retail Store website to contact them and couldn't send the message. Message just hung up all day. I think the connection is secure (icon next to Firefox address bar does not have a slash thru it so I think connection is secure). That Firefox icon says it is blocking trackers and cookies on the website and "Enhanced Tracking Protection" is "On". And got message in bottom corner of website saying "ERROR for site owner: Invalid domain for site key". Using up-to-date Firefox browser, Windows 10 and Windows Defender Firewall. (Tried Windows Edge browser and it said connection was insecure so I followed steps to connect to it like changing Privacy settings and switching to a Private Window but it didn't help.) What else can I try to use this Japanese website? (Note: website does not have an email address listed anywhere.)
