A set of userChrome.css themes for Mozilla Thunderbird inspired by the Monterail email client redesign mockups. It includes five color variants, a bundled font, and replacement SVG icons.
Use cases
- make thunderbird look modern and minimal
- apply a dark theme to thunderbird
- customize thunderbird colors and fonts
- replace thunderbird's default icons
- match thunderbird's appearance to my system theme
When to choose
- you want a polished, modern visual restyle of Thunderbird
- you prefer dark or system-matching color schemes in your email client
- you are comfortable editing CSS variables to customize colors and fonts
When to avoid
- you need a theme compatible with the latest Thunderbird versions, as the project has not been updated since 2020
- you want a one-click installable add-on rather than manually extracting files into your profile's chrome folder
- you use a Thunderbird version where userChrome.css customization is disabled by default
