Slow P4Web Connection in Firefox on Vista

PROBLEM

Why is P4Web slower when I connect with Firefox under Windows Vista on my local machine?


SOLUTION

When using Firefox as your browser under Windows Vista, connecting to P4Web on localhost is slower than connecting remotely. Other browsers do not exhibit this symptom, and this does not affect connecting to a remote server running P4Web. Change the Firefox setting "network.dns.disableIPv6" to true to fix this slow connection. The following example shows the steps to change the "network.dns.disableIPv6" setting:

Example

  1. Type "about:config" in the URL "open location" field and press enter. You should see a raw list of Firefox settings.

  2. Type "disableIPv6" in the "Filter:" field. "network.dns.disableIPv6" should now be the only line listed.

  3. Right click on the "network.dns.disableIPv6" line and select "Toggle".
The new setting for "network.dns.disableIPv6" is now true. You should see an immediate performance improvement when connecting to P4Web on localhost.
