Firefox loads localhost resources slowly
If while debugging your Silverlight application using the Visual Studio web development server, you notice Firefox is painfully slow to load any resource, you might want to disable IPv6 support. This should get Firefox (<=3) working on par with Safari, IE, et al..
- Open Firefox
- Navigate to “about:blank”
- Find the entry for “network.dns.disableIPv6” and set it to false.
Now try loading your local development site! This applies to the general case of Firefox loading anything from localhost.
