+  Firefox requires Capsicum since r522464 for IPC and in future will
+  require Capsicum for process sandboxing. If you use a custom kernel
+  make sure to copy the following lines from GENERIC kernel:
+
+    options 	CAPABILITY_MODE		# Capsicum capability mode
+    options 	CAPABILITIES		# Capsicum capabilities
