Vienna Theme for Firefox

Inspired by Vienna's refined elegance and cultural heritage, this dark theme creates a rich, immersive coding atmosphere in deep velvet reds and warm burgundy tones. Subtle gold and soft rose accents add a sense of quiet prestige. The result is a calm, intimate environment built for long, uninterrupted sessions.
