Enabling features that are disabled by default in Firefox

Native events is such a feature:

It is disabled by default for Firefox on Linux as it may cause tests which open many windows in parallel to be unreliable. However, native events work quite well otherwise and are essential for some of the new actions of the Advanced User Interaction. To enable them:

FirefoxProfile profile = new FirefoxProfile();
profile.setEnableNativeEvents(true);
WebDriver driver = new FirefoxDriver(profile);
