Visual Studio Debugging - Waiting For Localhost

PROBLEM:
When debugging an ASP.Net application in Visual Studio 2010, launching the inbuilt webserver in Firefox is extremely slow and may eventually time out.

CAUSE:
An IPv6 DNS problem with Firefox

SOLUTION:
Load the about:config screen in Firefox and set network.dns.disableIPv6 to true.
