Kevin Menard (current maintainer of Selenium Grid) has posted a guide to using basic HTTP authentication in Selenium.

One way to get around this is to embed the user credentials in the URL. Traditionally this has worked well, but newer browsers have disabled that functionality due to the security risks inherently involved. Fortunately, there is another way: send over the authentication credentials in the request header.
