The problem
Using Firefox on Vista to view websites hosted by the Visual Studio Development Server can be unbearably slow. Pages take aeons (i.e. several seconds) to load while viewing the same site under IE does not suffer from this issue.
The solution
As mentioned in this blog post, this problem can be solved like this:
- Open the Firefox config (browse to about:config)
- Locate the setting: network.dns.disableIPv6 (type "v6" into the filter field)
- Change the value to true (double click the row)
The result
Now sites on the built in development server work fast even under Firefox and Vista.
The conclusion
What can I say - it works :-)
Update 06/19/2008: works with Firefox 3 as well
