This style is designed to be used with the Simple White X theme (https://addons.mozilla.org/en-US/firefox/addon/simplewhitex/). It gives you a colored Titlebar on Windows 10 if you have the option to show accent color on start menu/taskbar/action center/titlebar enabled. Note: Due to how the Min/Max/Close buttons are drawn this will probably only work properly with 100% DPI
Just square tabs...
This is a style which effects the skin of firefox. It's dark, flat, minimal and sexy. You need it!
