FOXSCAPEuC: FOXSCAPE theme for Firefox userChrome.css by Michael Walden

---

The only way to modify ui is adding custom CSS code to userChrome.css and userContent.css files inside browsers profile folder. Keep in mind CSS code can not create entirely new items, buttons or toolbars. Only already present ui items can be modified!

(CTR) = known from Classic Theme Restorer add-on
(CTB) = known from Classic Toolbar Buttons add-on

(NB) = known from NoiaButtons add-on look here
(N4) = known from Noia4 theme
(GMF) = known from GlassMyFox add-on (window transparency on Windows 8/10 can only be achieved by third party tools like Glass8)
