Firefox — The fast, private browser that keeps you safe

Firefox is a free, independent web browser built by a company that is not owned by shareholders and states it never sells personal data. It emphasizes automatic privacy protection (tracker blocking with no setup), user control over optional AI features, and focus-oriented browsing tools like tab groups, reader mode, and picture-in-picture video. It runs across desktop, mobile, and tablet, with synced tabs, history, and passwords, and offers an import flow that brings bookmarks, passwords, and history over from your previous browser.

Key Features

Automatic tracker blocking

Blocks trackers automatically by default — no setup and no guesswork — so privacy protection works from the moment you install.

Free built-in VPN

A free built-in VPN is included as part of the browser, per the product's own positioning.

Optional, controllable AI

AI features are optional by design: you can customize how AI shows up in the browser or turn it off entirely.

Focus and organization tools

Tab groups and Firefox View help manage open tabs, a customizable sidebar keeps frequently used tools one click away, reader mode strips distractions from articles, picture-in-picture keeps video out of the way, and pinned tabs keep what matters close.

Cross-platform sync

Take tabs, history, and passwords across desktop, mobile, and tablet; data stays encrypted by default and isn't tied to a single platform.

One-click import from other browsers

When switching, bookmarks, passwords, and history come over automatically so you can resume browsing immediately.

Extensions and themes

Access to over 30,000 extensions plus thousands of light and dark mode themes for customization.

Built-in PDF editing

Edit PDFs directly inside the browser without needing separate software.

How It Works

1. Download and install

Get Firefox from the website for desktop, or grab Firefox for your phone. Older systems (Windows 8.1 and below, macOS 10.14 and below) are directed to the Firefox ESR build instead.

2. Import your data

On first setup, choose what you want to bring with you and click import — bookmarks, passwords, and history transfer from your previous browser automatically.

3. Browse with protection on by default

Tracker blocking is active with no extra steps. Customize further with extensions and themes, organize with tab groups and the sidebar, and toggle AI features on, off, or configured to your preference.

4. Stay in sync across devices

Use Firefox on desktop, mobile, and tablet so tabs, history, and passwords follow you, encrypted by default.
