HTTPS "not secure" with Chrome

When running the following code, everything works fine, except that left of the URL Chrome displays “Not Secure” on HTTPS sites. How do I get rid of that?

BrowserMobProxy proxy;
WebDriver driver;

proxy = new BrowserMobProxyServer();
proxy.start();

final Proxy seleniumProxy = ClientUtil.createSeleniumProxy( proxy );
final String hostIp = Inet4Address.getLocalHost().getHostAddress();
seleniumProxy.setHttpProxy( hostIp + ":" + proxy.getPort() );
seleniumProxy.setSslProxy( hostIp + ":" + proxy.getPort() );

final FirefoxOptions fOptions = new FirefoxOptions();
fOptions.setCapability( CapabilityType.PROXY, seleniumProxy );
driver = new FirefoxDriver( fOptions );

final Har har = proxy.newHar( "https://google.de/" );
driver.get( "https://google.de/" );

List<HarEntry> entries = proxy.getHar().getLog().getEntries();
for (int i = 0; i < entries.size(); i++) {
      System.out.println("Response status: " + entries.get(i).getResponse().getStatus());
}

final WebElement searchTextField = driver.findElement( By.name( "q" ) );
searchTextField.sendKeys( "foo" );
System.out.println( "### HAR after sendKeys: " + har );
searchTextField.submit();
System.out.println( "### HAR after submit: " + har );

proxy.stop();
driver.close();

I’m using ChromeDriver 2.44.609545 and browsermob-core 2.1.5.

ChromeOptions options = new ChromeOptions(); options.setCapability(CapabilityType.PROXY, seleniumProxy); options.addArguments(“–ignore-certificate-errors”);
