Custom styling

The theme comes as is but it can be extended using CSS files provided in the custom folder. Further extensions should be included in the same folder to keep the main theme consistent. To enable custom styles, copy and paste the following @import statements at the end of the userChrome.css file.

Re-enable title bar controls (MIN-MAX-CLOSE buttons)

For Windows:

@import "custom/_titlebar-controls-enable-windows.css";

For macOS:

@import "custom/_titlebar-controls-enable-macos.css";

Disable megabar behavior

@import "custom/_megabar-disable.css";

Add Developer Tools styling

Set theme to dark in Firefox Developer Tools settings. Then, add the following line to userContent.css:

@import "custom/_dev-tools.css";
