Good morning Martijn,

Are you using Firefox 10?

There appears to be a bug in Tomcat 6 (should be fixed with newer
releases of Tomcat 6) which is triggered when Firefox 10 is used.

Can you change the protocol setting from:

protocol="org.apache.coyote.http11.Http11NioProtocol"

to:

protocol="HTTP/1.1"

in the file /etc/tomcat6/server.xml

and check whether this solves the problem.

thank you!
Changing the protocol line fixed the problem.

Kind regards,

Stefan
