'''Question: Firefox favicon.ico issue'''
 There is a known [[https://bugzilla.mozilla.org/show_bug.cgi?id=519028|issue]] with Firefox and how works with java security.

Add an empty security constaint into your web.xml file for favicon.ico. Here is an example

{{{
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/favicon.ico</url-pattern>
</web-resource-collection>
</security-constraint>
}}}

By leaving the <auth-constraint> tag out, anyone is allowed to access this file.
