try using Browser Toolbox to find the tab element, and then adding something like:
border-top: 4px solid blue
to that element in the userchrome css.
btw, enabling browser toolbox is a bit tricky, you have to enable "remote debugging" in the ctrl shift i settings, and then ctrl alt shift i to open it
