Under tools/options - content. There is a button that allows you to set the color of used links. The color difference between new & used links is not enough for me on my system. Setting a usable color does not work on most web pages [mozilla's included] unless you uncheck the box that "Allow pages to choose their own color..." Then when you do this, it screws up the entire display of Google, Mozilla, and others to the point where some buttons, check boxes, etc simply do not work. What can be done to show used links with more contrast?
