You can ignore (CSS) errors in the Tools > Error Console.
Those errors are only useful if you develop websites and want to check the HTML/CSS and JavaScript code for errors.
Most errors are code for other browsers like IE or browsers on other platforms or just typos or the result of bad coding.

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