When using Firefox as the default web browser, and developing apps with the built in webserver in Visual Studio 2008 / 2005, then Firefox loads your app fuggin’ slow ..
This problem has been around for ages – or atleast back to to Firefox 2.x.x days. It is caused by some interplay between Firefox’s ipv6 support and the Microsoft’s development web server (codename Cassini I think). Anyhow the solution is easy: disable ipv6 in Firefox (since at the time of writing ipv6 isn’t used at all really this is a safe thing to do).
- Type “about:config” in the address bar in FF and press Enter.
- Answer yes to void your warranty in FF3.5 (you know what you’re doing right?)
- Search / filter for “ipv6”, then click on the option “network.dns.disableIPv6” to disable it (value true).
- Restart FF.
