+  The default Gecko provider has been changed from www/firefox to
+  www/libxul.  Firefox 2.x is now forbidden for security reasons, and
+  libxul is the new, stable Geck provider.  Libxul uses the same Gecko
+  engine as Firefox 3.0.x.
+
+  Some ports may fail to upgrade or run when both www/firefox and libxul
+  are installed on the same system.  To make sure everything runs smoothly,
+  uninstall www/firefox, then install libxul, then upgrade the affected
+  ports.
