As stated in the comment. If you use FF, you can specify the profile to be used.
How to do this, it sets browserStartCommand (the third argument to the DefaultSelenium constructor) like this:
*custom "C:/Program Files/Mozilla Firefox/firefox.exe" -no-remote -profile "C:/Some/Path/To/Mozilla/Firefox/Profiles/selenium"
And in this profile you can disable cookies.
