It's too soon for this as Selenium HtmlUnit doesn't yet support Selenium 4.0.0.

According to https://github.com/SeleniumHQ/htmlunit-driver#version-3xx there is a new version now, that should be compatible with Selenium 4.

@wilkinsona Could this issue be reopened or are there any other plans for Selenium 4 integration?

Thanks for the info, @sepe81. We'll pick it up automatically once we've started work on 2.7 and kick off the dependency upgrade process.
