Cupertino: Unofficial macOS theme for Firefox автор Corbin Davenport

Cupertino is a theme for the Mozilla Firefox browser designed to match the macOS color scheme and design. It provides a slightly more native look and feel for Firefox on Mac computers, inspired by the design of Apple Safari, and it supports both light and dark modes.

The developers of this theme are not associated with Mozilla or Apple, inc. The code is open-source on GitHub.
