Error 623: The system could not find the phone book entry for this connection
When trying to use Firefox offline to view HTML files saved to my local machine, I get a dialog box:
Network Connections Cannot load dialog.
Error 623: The system could not find the phone book entry for this connection.
This happens several times at startup (if addons are loaded) and also when trying to access the Tools > Options dialog box.

See http://kb.mozillazine.org/Autoconnect
In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings".
See "Firefox connection settings" in Server Not Found - Troubleshoot connection problems
You can find the connection setting here: Tools > Options > Advanced : Network : Connection Try to select No Proxy
