This error occurs in Ajax requests (jQuery 1.7.1) when I use Firefox 10.0. But there is no error in FF 8.0, IE 7-9 and last versions of Opera and Chrome.

May not be related to your problem but some of your Firefox Plugins are out-dated

  • Update All your Firefox Plugins -> https://www.mozilla.org/en-US/plugincheck/
  • When Downloading Plugins Update setup files, Remove Checkmark from Downloading other Optional Softwares with your Plugins (e.g. Toolbars, McAfee, Google Chrome, etc.)
