B.1 SSL VPN Fails to Load If Firefox 3.0 Is Used on Vista 64-bit

When a user tries to connect to SSL VPN by using Firefox 3.0 (32-bit) on Vista 64-bit, the SSL VPN applet fails to load. This is because Sun JRE 1.6 Update 12 additionally bundles a newer Java plug-in for Firefox, so some applets fail to load.

To work around this problem, disable the newer Java plug-in and roll back to the older plug-in as follows:

  1. Open the Java Control Panel in one of the following ways:

    • Browse to <Install_Folder>\Java\jre6\bin, then run Javacpl.exe.

    • Go to Start > Control Panel > Java.

  2. Select Advanced > Java Plug-in and deselect Enable the nextgeneration Java plug-in.

  3. Select Advanced > Default Java For Browsers and make sure that MozillaFamily option is enabled.

  4. Restart the browser.
