Following browsers are limited supported:

Microsoft Internet Explorer, automated directory online only, mp3 and PDF
Microsoft Edge, automated directory online only, mp3 and PDF

Microsoft does not support offline automated directory so you cannot use this website if you have downloaded it. If you try it will open every folder with Windows Explorer. Online from the webserver it just works fine.

Although Microsoft displays text it does not accept the Linux newline as a newline. Microsoft uses a different standard since MS-DOS and needs both carriage return followed by a newline character. This means with Microsoft you probably will have to scroll horizontally while reading this since everything is just put on one line.

Although Microsoft displays PDF in the browser it is of such bad quality that you should download it and display it with for example Adobe Acrobat.

Therefore Microsoft Browsers are not supported.
