## What it is
ShyFox is a Firefox userChrome CSS theme that hides the entire browser interface into the window border for an ultra-minimal look, with vertical tabs via Sidebery integration. It is configured through CSS variables and about:config options.

## Use cases
- hide firefox browser chrome completely
- vertical tabs in firefox with sidebery
- minimalist firefox theme
- customize firefox userchrome css
- make firefox look like a borderless window

## When to choose
- you want a maximally minimal Firefox UI hidden in the window border
- you use Sidebery for vertical tabs and want it styled to match
- you like tweaking themes via CSS variables and about:config flags

## When to avoid
- you need a maintained theme - the project is currently unmaintained and may break with new Firefox versions
- you don't want to install userChrome.css tweaks manually
- you rely on a traditional visible toolbar/tab bar

- function: theme, ui-components
