# Cortland

A sleek, modern, macOS-inspired theme for Firefox.

![image](/screenshots/cortland-screenshot.png)

## Description

This is is a collection of CSS code that changes the look and feel of Firefox. 

Cortland turns the default UI of Firefox into an intuitive, modern interface, and supports both both light and dark themes, too!

This theme currently supports MacOS and Linux. Windows is not supported (yet). Firefox 70+ is recommended. 

## Installation

1. Download this project.

2. Go to about:support in Firefox.

3. Under `Application Basics` > `Profile Directory`, click the `Open Directory` button.

4. Copy the `chrome` folder from this project into the profile directory folder.

5. Go to about:config. 

    * Click `Accept the Risk and Continue`. 

    * Search for `toolkit.legacyUserProfileCustomizations.stylesheets` and set it to `true`.

6. Open the Firefox menu (☰), click `More tools`, and then click `Customize toolbar...`. If you are using an older version of Firefox, simply open the menu (☰) and click `Customize...`. 

    * Ensure that the `Title Bar` checkbox is unchecked. 

    * Drag the new tab button out of the tabbar and into the headerbar.

7.  Go to about:addons.

    * Click on the `Themes` button in the sidebar.

    * Look for `System theme - auto` and click `Enable` if it is disabled.

9. Restart Firefox.

10. Enjoy your new Firefox theme!
