Misconfiguration at Island Hosting > as Firefox suggests? You've got three different URLs here, which means you're looking at three different web sites. https://hornby.islandhosting.com:2096 https://mail.easthope.ca:2096 https://158.69.159.172:2096 Each of these may give you a different web site, even if they're all hosted on the same physical computer, or the same virtual machine. So, it's conceivable that Mozilla has flagged one of these web sites as a security risk, but not the other two. It's also conceivable that Mozilla has flagged an entire block of "raw IP address URLs" as a security risk, based on a pattern of behavior that they've seen from other web sites within that address range. You'd have to ask Mozilla for the exact details about why they've flagged what they've flagged.
