Question: Firefox favicon.ico issue
There is a known 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.
