   <div class="markdown level0 remarks"><p>When the FirefoxDriver object has been instantiated the browser will load. The test can then navigate to the URL under test and
 start your test.</p>
 <p>
 In the case of the FirefoxDriver, you can specify a named profile to be used, or you can let the
 driver create a temporary, anonymous profile. A custom extension allowing the driver to communicate
 to the browser will be installed into the profile.
