You also have some out-of-date plugins with known security issues. You need to update your plugins. It is important to keep them updated due to continuing security fixes and improvements in those plug-ins:

• Shockwave Flash 10.0 r32
• Next Generation Java Plug-in 1.6.0_17 for Mozilla browsers

1. Check your plugin versions: http://www.mozilla.com/en-US/plugincheck/

2. Update Shockwave Flash
   • Use Firefox to Download and SAVE to your hard drive from one of the links below; the links take you directly to the download and you avoid the "getplus" download manager and "extras" (i.e., toolbars, virus scan links, etc.) on the main Adobe page.
   • SAVE to your Desktop so you can find it
   • After download completes, close Firefox
   • Click on the file you just downloaded and install
     • Note: Vista and Win7 users may need to right-click the installer downloaded and choose "Run as Administrator"
     • Note: Most browsers other than IE will also get updated with this one download
     • Note: To update IE, same procedure but use IE to go: http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_ax.exe
   • After installation, restart Firefox and check your version again.
