LumaTab от Sajid Alam

LumaTab for Firefox,
Turn every new tab into something calm, beautiful, and genuinely useful — with zero tracking.

What you get:
Living wallpapers — 15 canvas-rendered scenes (aurora, rain, snow, ocean, cyber city and more) with smooth parallax and mouse light.
Automatic theming — the whole interface (accent, glass, text, glow) adapts to your wallpaper. Override the accent anytime.

A personal widget grid — weather, notes, to-do, quick links, bookmarks, world clock, focus timer, system stats, calendar, downloads, history, recently closed tabs, clipboard and RSS feeds. Drag to reorder, resize, or hide each widget.
Smart search — Google, DuckDuckGo, Brave, Bing, YouTube, Wikipedia, GitHub, ChatGPT, Perplexity, plus custom engines, with optional live suggestions.

Full settings page — appearance, themes, widgets, search, animations, performance, privacy, and profile backup/import/reset.

Privacy first
