I was wondering if there are any add-ons or mods for Firefox 25 that would allow me to change the colour of the icons on the navigation buttons. I'm thinking along the lines of the older style where the back and forward buttons would light up green, reload in blue, stop in red, and home with a white/yellow mix, when they are clickable. I find with Firefox 25, I get light gray when grayed out, and dark gray when active, which I find is a bit difficult to tell at a glance. I prefer the colour-coded buttons, and was hoping there was an add-on that would allow me to change that in Firefox 25.
