Unable to use Security Settings

I have install Adobe Reader 9.5.4 (.deb) from the adobe website

When I try to use Document - Network Settings I always get 'Unable to find HTML Rendering library'

I configured the Rendering Library under Preferences - Internet (I use libxul.so) the Adobe Reader chrashed.

I run Adobe Reader on Debian Wheezy.

Any ideas how to get this solved?

many thanks
