The issue where IE wouldn’t work? Well Microsoft smartly decided that IE should APPEND the urls to the current page URL where EVERY OTHER BROWSER used the relative url properly.
Edge, Safari, Chrome, Opera, and Firefox would call the url properly, but not IE (as you can see in the description).
Either way this is fixed for IE too.
For the Firefox issue you’re seeing, it would seem to me the NAS is redirecting and handing out its own output page which is why it’s showing up funny. I cannot help that at all.
