MXR -> DXR
HINT: It might be tempting to look at searchbar.css, but that only styles the small input bar where you can quickly access major search enginges. You should look at browser.css, which contains the styling rules for the majority of the Firefox user interface.
===Use MXRDXR===
It turns out that browser.css has a lot of rules in it. Let's narrow down the actual rule we want to change.
It's time to use MXR[https://dxr.mozilla.org/ DXR], the Mozilla Cross Reference tool. You can search for "browser.css" and take a look through the results; see if any of the files that show up look like good candidates!
HINT: You can focus on XUL and XML files, which are used to define Firefox's user interface. Often, CSS files share filenames with the files that they are styling - in this case, browser.xul looks like a good match.
