You will have to close and change the pref via user.js or prefs.js before restarting Firefox to do the next test.

You do not have access to prefs via JavaScript on websites or via a bookmarklet. Only extensions are able to change prefs.

See http://developer.mozilla.org/en/Code_snippets/Preferences


Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

  1. Shockwave Flash 10.0 r42
  2. Java Plug-in 1.5.0_15 for Netscape Navigator (DLL Helper)

Update the Flash plugin to the latest version.

Update the Java plugin to the latest version.
