FireVerse OS Get the add-on

Firefox 140+ · Chrome build ready

Your tab.
Your rules.
Your universe.

FireVerse OS replaces the blank new tab with a dashboard you actually use — widgets, themes, bookmarks, history, downloads, tasks, notes and an AI assistant that talks straight to a provider you choose. No account, no server, no tracking.

The dashboard

One tab. Everything in reach.

FireVerse OS turns a blank page into a working surface. Personalize it, organize everything you keep in the browser, then get out of the way.

01

Personalize

Six themes, four density modes, canvas effects and your own wallpaper. The tab should look like it belongs to you.

6 themes · 4 effects
02

Organize

Bookmarks, history, downloads, notes and tasks live in one calm surface, with search that actually finds things.

One search · every panel
03

Focus

Pomodoro, reading mode and performance modes keep the browser out of your way when it matters.

Ultra to Battery Saver

Themes & effects

Change the room, not the workflow.

Cosmic, cyberpunk, holographic, neon, dark and light. Layer aurora, particles, starfield or matrix effects behind glass widgets — then dial the blur and brightness to taste.

  • Six built-in themes, plus your own wallpaper
  • Four canvas effects that respect reduced motion
  • Glass, blur and brightness controls

What’s inside

Built for the way you browse.

A dashboard is only useful if it holds the things you already do. Every panel is one click away, and every pixel stays on your machine.

AI assistant chat with a provider you choose. Direct to provider
Opt-in only

An assistant that never sees your keys.

Chat with OpenAI, Gemini, Anthropic, Groq or a local model. Requests go directly from your browser to the provider you configure.

Browsing history with a timeline heatmap. On-device
Local

A timeline of where you’ve been.

History with a heatmap and top-site stats, read straight from Firefox and never transmitted.

Bookmark manager with a visual grid.
Bookmarks

Everything you saved, finally findable.

A visual grid with search and starred favourites.

Download center grouped by file type.
Downloads

Every file, sorted.

File-type categories, search and quick stats.

Performance modes from Ultra to Battery Saver.
Performance

Modes that match your machine.

Ultra, High, Balanced and Battery Saver, with auto-adaptation to frame rate.

Privacy

Private by architecture.

FireVerse OS has no servers, no accounts and no telemetry. No analytics SDK, no crash reporting and no tracking code. Bookmarks, history, downloads, tasks and notes are read from Firefox and stored locally on your device.

0 servers
0 accounts
0 trackers

Two features can send data off your device: the weather widget and the AI panel. Firefox asks for permission the first time you use either one, and you can withdraw it at any time. Declining costs you that one feature and nothing else.

Opt-in by design

Nothing leaves without consent.

Weather and AI are the only outbound features. Both are requested at the moment of use and withdrawable in Permissions and data.

Your key, your data

No proxy in the middle.

AI requests go directly from your browser to the provider you pick, with your own API key. Prompts and keys are never proxied, logged or billed by us.
