+### Headless
+
+Firefox has a headless feature that can be accessed directly with: 
+
+{% highlight ruby %}
+b = Watir::Browser.new :firefox, headless: true
+{% endhighlight %}
+
+However this syntax is deprecated by Selenium so the following syntax should be prefered.
+
+{% highlight ruby %}
+b = Watir::Browser.new :firefox, options: {args: ['-headless']}
+{% endhighlight %}
+
+It also possible to use [the Headless gem](/guides/headless/).
