Providing additional functionality to multiple classes

Selenium has multiple classes providing mechanisms for certain browsers.

So there are the following drivers (I care about most): FireFoxDriver, ChromeDriver, InternetExplorerDriver,

All of these, inherit from RemoteWebDriver.

public class FireFoxDriver : RemoteWebDriver { ... }
public class ChromeDriver : RemoteWebDriver { ... }
public class InternetExplorerDriver : RemoteWebDriver { ... }

Now, I would like to provide additional functionality/helpers to each driver such as, for example, going to URL and executing the script:

public void Goto(string url)
{
    Navigate().GoToUrl(url);
    ExecuteScript("console.log('Using selenium');");
}

I want to have this functionality for every driver (either FireFox, Chrome and IE) so I could do:

var chrome = new ChromeDriver();
chrome.Goto("https://google.com/");

So yeah, what is the proper way to do that?

Basically, I could get it working with creating a BaseRemoteWebDriver class, put my functionality in there and then create a BaseChromeDriver, BaseFireFoxDriver, BaseIEDriver and inherit from BaseRemoteWebDriver.

This way, I could perhaps achieve what I want, however I would endup having three, basically empty classes that inherit from BaseRemoteWebDriver, containing only generated constructors.

Is this the only (valid) way to extend the classes in C#?

You could also use Extension Methods.

Then you could write something like this:

public static class RemoteWebDriverExtensions
{
    public static void Goto(this RemoteWebDriver driver, string url)
    {
         driver.Navigate().GoToUrl(url);
         driver.ExecuteScript("console.log('Using selenium');");
    }
}

And then call it like that:

RemoteWebDriver chromedriver = new ChromeDriver();
chromedriver.Goto("https://google.com");
