Its the line with the Mozilla Firefox orange logo in the top left corner and the page information and in the top right corner is the - (hide window) ...and the 2 squares...and the big red X (close window). I want to remove this blue line but keep the top right buttons if i can. Its totally ugly and does not go with my PC theme at all. I've searched online but i can't find any solutions. I want my theme to cover my whole screen. Apart from this problem i like Firefox and don't want to switch to Chrome. Thanks for your advice.
