For webpages which are available in different languages the preferred languages can be set in Preferences/General/Languages. Unfortunately this does not work for me. Although I have set de-de (German) as prefered language the page http://www2.uibk.ac.at/fakultaeten/ is always displayed in english. I guess the problem is that the browser identifies itself as Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.12) Gecko/20050922 As you can guess I have an english version of firefox installed. Is there a way to change the browser identification string? Or could the problem be located somewhere else?
