Looking at the Error Console was the right idea, thanks. Here's the
error that is caught when clicking the "Confirm Security Exception"
button:

Exception { name: "NS_ERROR_FAILURE", message: "Component returned
failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIURI.port]", result:
2147500037, filename: "chrome://pippki/content/exceptionDialog.js",
lineNumber: 156, columnNumber: 0, data: null, stack:
