So, I have gotten superpins (newer version has things not in the image but I sorted those out), then I got to the CSS. I did the steps of doing "about:support," then opening the user file and dropped the "userChrome.css" file in the "chrome" folder in. But nothing worked after restarting. I cant tell if I need something else or I did something wrong. Do I need to add anything else or install anything extra?
