You’re right that it removes the color bars, so I’ve commented out that line as optional. But as far as I know, this CSS doesn't hide any site-specific privacy-related controls. Which ones are you referring to? Note on the color bars: I'd rather not have extra noise in the tabs because I determine which container I’m in through the address bar and automated domain containers. Of course, for someone who wants an overview of how many tabs are in each container, the color bars might be useful. It's a good point that this might be unexpected, even though it's noted in the CSS. So I've commented out that line and will let people enable it themselves.
