Nightify - Beautiful Dark Mode

🌙 Nightify — Browser Extension ✨ Transform any website into a beautiful dark mode experience. Nightify is a Firefox extension that puts you in full control of how every website looks. One click to activate, then fine-tune everything to match exactly how you like to browse — day or night.

😣 The Problem The web is built bright. White backgrounds everywhere, harsh contrasts, blinding screens at 11pm. Your eyes pay the price. Most dark mode tools are either too aggressive — breaking layouts, hiding videos, turning pages completely black — or too basic to be useful. Nightify gets it right.

⚡ What It Does The moment you install Nightify, every website gets a smooth, intelligently applied dark theme. Not a crude color overlay — a real theme that respects the page's layout, keeps your videos visible, and never breaks what you're looking at. You get a clean popup panel with four tabs: 🎨 Filters, 🖥️ Display, 🌐 Sites, and ⏰ Schedule. In 🎨 Filters, you can dial in exactly how dark, warm, blue-light-filtered, or contrasty you want your screen. Eight one-click presets — 🌙 Default, 🌃 Night, 🕯️ Warm, ❄️ Cool, 🎯 Focus, 🔅 Dim, 📖 Reading, 🎬 Cinema — cover most situations instantly. Seven sliders let you go further. In 🖥️ Display, you choose how deep the transformation goes. Smart Invert flips the whole page dark while automatically keeping images and videos looking natural. Adjust font size, line spacing, content width. Toggle transitions, scrollbar styling, and more. In 🌐 Sites, you exclude any website where you want the original look preserved. Set a custom brightness just for that one site. One toggle disables Nightify entirely on the current page. In ⏰ Schedule, Nightify turns itself on and off automatically — either following your operating system's 🔄 dark mode, or on a custom 🕘 time range you define.

🔒 Completely Private No servers. No accounts. No telemetry. Everything stays in your browser, locally, always.
