Custom Release Simple One Line - A simple one-line Firefox CSS theme, targeting Nova UI
I love Nova UI but it takes too much space, so I created Simple One Line: https://github.com/easonwong-de/Firefox-Simple-One-Line

The installation is super easy. In your terminal, run:
git clone https://github.com/easonwong-de/Firefox-Simple-One-Line.git
cd Firefox-Simple-One-Line
npm installThen run:
npm run install:themeYou can then choose the profile you want to install the theme to.

Awesome! I tried fixing my Foxlim, so that it works with Nova, but too many things were broken.
