I get a message "Java (or Smartupdate) must be enabled to install Yahoo! Canada Toolbar".
To enable Java:
Go to the "Edit" menu, choose "Preferences" option, select the "Advanced" category and make sure "Enable Java" is checked.
To enable Smartupdating: Netscape 4.0: Go to the "Edit" menu, choose "Preferences" option, select the "Advanced" category and make sure "Enable AutoInstall" is checked.
Netscape 4.5+: Go to the "Edit" menu, choose "Preferences" option, select the "Advanced" category and make sure "Enable SmartUpdate" is checked.
