How to adapt the security settings of Opera 9
Opera 9 allows the user to define site-specific settings. Users who want to ensure maximum security should therefore disable the display of all active content - such as Java, JavaScript or plug-ins - as well as cookies by pressing the F12 key to access the "Quick preferences".
If users experience problems when viewing a trusted site, they can enable the required technologies by also pressing F12 and then selecting "Edit site preferences..." to enable Java, JavaScript, plug-ins etc., for the currently displayed site (the site that the browser is displaying).
