Thank you for the feedback, Stephan Sokolow. We're glad your tweaks are working for you.
It's not that I want to say "Hey, I'm using userChrome.css!"
Rather, that I was trying to say "It'll be very important to make sure that the presence (and, ideally, nature) of a userChrome.css is taken into consideration when gathering data." and giving an example of how big a difference it can make in the user's perception of the browser.
