Death & Life de osmn-byhn

Death & Life is a minimalist Firefox theme inspired by the Japanese concept of mortality and existence (死 · 生). It transforms your browser with a striking monochrome black-and-white aesthetic and diagonal duality design.

What you get:
• Dynamic browser chrome — diagonal black & white skins for the toolbar, vertical tab strip, and URL bar
• Custom new tab page — cherry blossom wallpaper, elegant search bar, and a split clock widget (Death / Life)
• Search integration — uses your Firefox default search engine, no third-party tracking
• Vertical tabs support — styled sidebar tab strip with white active tabs on black chrome
• Zero data collection — everything runs locally in your browser

Perfect for users who love Japanese minimalism, dark themes, and clean new tab experiences. No accounts, no analytics, no external scripts — just a beautiful, focused browsing atmosphere.
