## What it is
Mozilla's Fira type family (Fira Sans and Fira Mono), originally designed for Firefox OS, distributed as font files with a CSS stylesheet for web embedding. The project is officially deprecated and unmaintained.

## Use cases
- download the Fira Sans font family for a website
- embed Mozilla's typeface via a CSS stylesheet
- find a monospace coding font for code editors
- use the Firefox OS typeface in a design project
- self-host Fira fonts instead of Google Fonts

## When to choose
- you want the Fira Sans or Fira Mono typefaces for web or desktop use
- you need a humanist sans-serif with matching monospace companion
- you want to self-host fonts rather than rely on a CDN

## When to avoid
- you need an actively maintained font project with ongoing fixes
- you want variable fonts or the latest Fira Sans releases (use Google Fonts instead)
- you need a license with clear terms (this repo's license is non-standard)
