Page Info not available if credential prompt shown

Opening a simple web page protected with IIS authentication Firefox pops up a credential prompt. At that moment I cannot check if connection secure as Page Info is not available, as well as any other Firefox option or shortcut. That could be by design but extremely unfriendly as how can I know site is secure before type my credentials?

Sample site that is doing that?

Well, it is mostly applicable to the sites where, for example, we use Windows authentication. Or login to O365 using SSO we can be prompted with credential.

Page Info probably wouldn't help in such a case because the domain in the current tab might be different. If you aren't sure then cancel the prompt to get an error page and access Page Info or the Network Monitor.

Thank you for the idea. Unfortunately it doesn't look like a solution because even if I cancel and check the page info next time when I login how do I know I'm connecting to the same site/page? Frankly the issue easily reproduce on all other browsers as well so I suspect that is a standard API like 'window.prompt" (https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt): "Dialog boxes are modal windows; they prevent the user from accessing the rest of the program's interface until the dialog box is closed."
