So you enjoy that good ol’ theme from Firefox versions past, with a touch up here and there?
You need to pick up Winstripe Modern then. I don’t know what it is, but something just feels right about this theme. It works for me on a visual sense, and is still one of my top ten favorite themes. You might check the previews to get a closer look at the interface – but you know it, you love it – so why don’t you have it?
