Today, IE 11 stopped accessing the site, whilst Chrome and Firefox continued to

Answer 1

The easiest way to make IE11 work with localhost on windows 8 is by going in the internet options > Security and drop all those bars to the lowest level and disable Protected Mode. I'm only using IE11 to see if my developed websites work correctly, not for browsing the internet. For that I have Chrome/Firefox.

Internet Explorer 11 includes a new isolation technology called AppContainer which is used by the Enhanced Protected Mode feature of the browser. EPM/AppContainer network restrictions help mitigate attacks against the computer by preventing content in the Internet Zone from connecting to your local network or your local PC.

The problem you're encountering occurs when the zone settings are such that your Local PC's content is treated as Internet Zone. If you were to use the machine name (e.g. http://mypc or http://localhost) the content would load in the Intranet Zone and thus outside of Protected Mode and thus outside of the AppContainer.

The same feature prevents IE11 from using Fiddler in your scenario; you can learn more about this issue here: http://fiddler2.com/blog/blog/2013/08/02/fiddler-and-internet-explorer-11-on-windows-8-1

To resolve this issue, use the Win8 Config tool at the left of Fiddler's toolbar (or download the standalone EnableLoopback tool from http://blogs.msdn.com/b/fiddler/archive/2011/12/10/fiddler-windows-8-apps-enable-loopback-network-isolation-exemption.aspx)
