Cobalt2 for Thunderbird

Jump straight to: Install Cobalt2 for Thunderbird

An unofficial faithful re-implementation of Cobalt2 for Thunderbird.

Key Features and Design Philosophy

• User interface colors provided by the official VSCode theme
• Contrast and minimalistic use of accent colors is first priority
• Patches missing theme properties in Thunderbird's extension framework in order to keep the theme consistent across all parts of Thunderbird
• Supports only latest Thunderbird ESR builds, no backwards compatibility
