This started happening all of a sudden on certain websites. I have school training I need to finish and I cannot load the modules anymore.... my laptop is brand new as of December 2010! I have the newest version of Firefox, the newest Adobe Flash, and the latest update for Java.

The message about CVE-2009-3555 is meant for webmasters to make them aware that they need to fix their servers.
Firefox 3.6 versions can detect such a misconfiguration and displays a warning in the "Tools > Error Console".

See:

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.
