Hi, I recently installed firefox in a RH 6.5 server. When I try to open the browser I get the error /usr/lib64/firefox/firefox: symbol lookup error: /usr/lib64/firefox/libxul.so: undefined symbol: gdk_window_get_visual This is my configuration [root@server1 ~]# rpm -qa nspr{-devel,} firefox xulrunner xulrunner-17.0.10-1.el6_4.x86_64 firefox-31.2.0-3.el6_6.x86_64 nspr-4.10.6-1.el6_5.x86_64
