When I access this site using MS Edge or Google Chrome, I get the website is not configured properly.

When I access the site using Firefox (59.0), no download is started. No messages are displayed. When I access the site using Edge or Chrome, I get the website not configured properly message.
I am using Windows 10, and ZoneAlarm.
I only get this error when trying to download the firefox update, 59.0.1, from mozilla.
The fact that you are getting it with Edge and Chrome also means it is not a issue with Firefox.
The https://www.mozilla.org/en-US/firefox/all/ is not the issue.
Zonealarm or some other security related software may be affecting your https:// connections as above article is example of that.
Also make sure your time/date is correct on your Windows.
You can try from http://archive.mozilla.org/pub/firefox/releases/59.0.1/win64/ as just pick the folder for your language. This will be the full setup and not the small online stub installer.
