usually there isn't a "chrome" folder inside the Firefox profile but if you already have one you know what to do
so just add the content of the userChrome.css and the png image inside your chrome folder

in the first case move the "chrome" folder LIKE IT IS 

into > yourusername \ APPDATA \ ROAMING \ MOZILLA \ FIREFOX \ PROFILES \ ********.default
