+ *
+ * <h3>Capabilities</h3>
+ *
+ * <dl>
+ * <dt><code>acceptInsecureCerts</code> (boolean)
+ * <dd>Indicates whether untrusted and self-signed TLS certificates
+ * are implicitly trusted on navigation for the duration of the session.
+ *
+ * <dt><code>pageLoadStrategy</code> (string)
+ * <dd>The page load strategy to use for the current session. Must be
+ * one of "<tt>none</tt>", "<tt>eager</tt>", and "<tt>normal</tt>".
+ *
+ * <dt><code>proxy</code> (Proxy object)
+ * <dd>Defines the proxy configuration.
+ *
+ * <dt><code>setWindowRect</code> (boolean)
+ * <dd>Indicates whether the remote end supports all of the resizing
+ * and repositioning commands.
+ *
+ * <dt><code>timeouts</code> (Timeouts object)
+ * <dd>Describes the timeouts imposed on certian session operations.
+ *
+ * <dt><code>strictFileInteractability</code> (boolean)
+ * <dd>Defines the current session’s strict file interactability.
+ *

+ *
+ * <dt><code>moz:debuggerAddress</code> (boolean)
+ * <dd>Indicate that the Chrome DevTools Protocol (CDP) has to be enabled.
+ *
+ * <dt><code>moz:useNonSpecCompliantPointerOrigin</code> (boolean)
+ * <dd>Use the not WebDriver conforming calculation of the pointer origin
+ * when the origin is an element, and the element center point is used.
+ *
+ * <dt><code>moz:webdriverClick</code> (boolean)
+ * <dd>Use a WebDriver conforming <i>WebDriver::ElementClick</i>.
+ * </dl>
+ *
+ * <h4>Timeouts object</h4>
+ *
+ * <dl>
+ * <dt><code>script</code> (number)
+ * <dd>Determines when to interrupt a script that is being evaluates.

+ * <dt><code>pageLoad</code> (number)
+ * <dd>Provides the timeout limit used to interrupt navigation of the
+ * browsing context.
+ *
+ * <dt><code>implicit</code> (number)
+ * <dd>Gives the timeout of when to abort when locating an element.
+ * </dl>
+ *
+ * <h4>Proxy object</h4>
+ *
+ * <dl>

+ * <code>proxyType</code> is equal to "<tt>pac</tt>".
+ *
+ * <dt><code>httpProxy</code> (string)
+ * <dd>Defines the proxy host for HTTP traffic when the
+ * <code>proxyType</code> is "<tt>manual</tt>".
+ *
+ * <dt><code>noProxy</code> (string)
